I'd guess this means they will be implementing new skills for each class and/or modifying the existing skills.  Here are some interesting extracts from the release notes for the new book that relate to Monster Play:

"Mischief" is now usable while mounted.

“Clobber” has been changed to deliver the induction interrupt at the same time as the damage instead of on a separate attack.

New skill! “Fear Nothing” is available at Level 46. It removes up to 3 Fear effects from the Champion and adds two Fervour pips. It has a 5 minute cooldown.

Because of changes to the Disarm effect, Hedge will now give a bonus to Parry and enable Parry for a short time, even in Fervour Stance.

Guardians gain a new skill at level 44. “Ignore the Pain” removes up to 3 Wound effects from the Guardian. It has a 5 minute cooldown.

Guardian’s “Protection” and ”Shield Wall” skills are now usable while mounted.

The Hunter now has two new skills!

• “Blood Arrow,” a ranged attack with significant critical damage, is available at level 44. It costs 3 Focus and uses Morale instead of Power. It has a 10 second cooldown.
• “Dazing Blow,” a melee attack that dazes the target for 5 seconds, is available at level 48. It has a 1 minute cooldown. This skill receives an upgrade at level 52 that enables it to remove 3 Corruptions.

The skill Blindside will now interrupt an induction.

“Ancient Wisdom” is now usable while mounted.

The range at which monsters detect players has been reduced across the board to improve the playability of camps and landscape.

Monster AI has been tweaked to significantly decrease the chance of being disarmed immediately after having just been disarmed.  [This damn well better be implemented for freep NPCs are well, sick to death of chain disarms in EC]

All food will now modify In-Combat Regeneration ratings instead of pulsing a heal or power restore every 30 seconds.

Wonder what the class changes mean - possibly a new class?

Illy, I'm not saying the sky is falling, just that some of the changes have the potential to affect play in the Moors.

Fanatics are always willing to spend real money to gain a pixelated advantage, especially in a PvMP environment like the Moors.  Will all freeps be able to spam the new HoT and PoT pots all the time?  No.  Will some freeps spam them in certain PvMP situations (1v1s, tight flag room fights, etc.)?  You bet your ass they will.  The bottom line is that Turbine never should have allowed them to be used in the Moors, period.  And the new stun dot functionality for LMs is going to have ramifications for freepside that dwarf those of the new HoT and PoT pots.

My morale pots have helped save my ass in both 1v1/small group and raid settings (less so in raids, but still they occasionally make a difference).  Now every freep who enters the Moors, regardless of rank, will have access to morale and power pots that are better than the ones that only Rank 9+ creeps can obtain (and have to grind hundreds of stones for in the Delving).  As to the "coin and time" required to craft them, are you kidding me?  The larger kins have scads of crafters who are going to be churning out the new pots at high rates on a constant basis.  They will be just as commonplace and easy to get as the current crafted morale and power pots are for freeps.

As someone who has recently leveled a freep, I am very aware of the diminishing returns.  But it just isn't true that "+30 to every stat is almost negligible."  If you had access to an item that would raise all of your stats by 30 (including those you can't afford to buff up, like will and fate), are you telling me you wouldn't go out and get it?  And isn't it true that people currently do crazy things like run instances scores of times just to get items that add a few more points at the high end despite the diminshing returns?  In my view, the primary effect of the stat tomes and the purchasable virtues is going to be to strengthen those freeps in the Moors who are currently undertraited or undervirtued and bring them on more of a par with those who have already grinded everything, like you.  Moreover, as you acknowledged, they will make getting alts ready a lot easier.  Game-breaking?  No.  Game-altering?  Perhaps.

I will grant you that of all the freep classes getting buffs in the next book, Champions will benefit the least.  But Captains and Hunters are getting some fairly significant upgrades, with Guardians and Champions bringing up the rear (as usual).  Will it be like Book 12 again?  No.  Is it a definite upgrade?  Yes.  Oh, and I forgot to mention that with the new book, many more freeps are going to be running around with Level 65 second age weapons since the Symbols of Celibrimbor are going to drop at a much higher rate than they do now (and be available as skirmish rewards, as well).

-- Pots are for people with deep pockets, and a majority of players won't be able to spam these (thereby affecting gameplay out there as a whole)

-- Morale pots help in 1v1s/small group action, but in raid vs. raid content they mean very little at all.  Plus, they cost coin and time to get.  

-- +30 to every stat is almost negligible.  Might/Agi have ridiculously high rates of diminishing returns.  1 Vitality = 3 morale (5 for Guards and Wardens), which is only another +90 or +150.  That's not game-breaking at all.  Our Virtue ranks are all able-to-be capped at 10 right now.  Thus, purchasing virtue ranks will only matter if you're making an alt, and even then it confers an advantage of less time spent grinding, not becoming more powerful overall.

-- The changes are hardly significant, for Champs at least, and won't really impact game-play either.  The new skill is crap in the 'Moors.  Stacking Champ bleeds barely matters because they're all common damage, they need two different legacies (1 on the weapon, 1 on the rune) to be any good, they can't crit, they're COMMON damage, and most importantly Champs have to be within 5m of a target to use them.  If Hunters got some new, half-decent bleed that stacked alongside barbed arrow then there'd be cause for concern.  Worry not... when was the last time you saw 3 or more Champs in the same raid that knew how to play?  There's few of us these days that know how to do anything besides slot a 2h weapon and pray for crits while gold-tagging groups or the zerg.

/Rant off :D

Yea.... I was hoping that they would make them only useable in PvE but sadly they did not, I guess the freeps wanted an even easier easy mode fun time in the Moors. I do know that they pots are on a 20 second cooldown, and IIRC the heals do not stack, so in essence, yes they could have be healing themselves constantly, but at that rate, they would be spending BUTTLOADS of money on those pots (cause they are not cheap in the store and not craftable). So, hey, if the freeps want to spend $20 just so they won't die to me, well hell, go for it, while they sit there -$20, ima spend my $20 on a bottle of Jack and laugh at you :p

/rant off

It worked when Mirk came out. we actually got a lot of people at least all poors and a few goods. However, since the Moors are "back to normal" people want inf more than they want maps. (I know I have been slacking with my other chars as well about this.)

My predictions are basically the same as all of yours. We will see a decrease in wargs (vets will stay) more revahs will be running around like chickens with their heads cut off, and LMs will be everywhere...

But other than that, you know. same ole' same ole...

The only things that will affect the freeps comming back to moors is old content, deeds, hele and annuminas etc, I dont imagine they will do all of this 24/7.
