After doing dozens of pugs and some bis guild raids for ICC/Ruby Sanctum I conclude one inmportant deficit in maximizing dps - lack of demand from warrior/warriors and if there is no - rogue/rogues to normalize keeping 20% armor reduction debuff - (wariors - Sunder Armor, rogues - Expose Armor) and here is why. In nearly any major warior/rogue guide in this realm I keep reading bull**** about gearing up for 100% - 1400 atleast for wariors w/o mace spec. and rogues of armor penetration. This in terms of gemming cost fine 380 strenght from wariors and 380 agi for rogues similar to ferals and even more harmfull for hunters(since arp doesn't boost their dmg so hard through "magical abilities". Let's now do abit of math - 380 strenght from wariors, which = with 5/5 talents from Improved Berserking Stance(increases strenght by 20%) either 380 strenght*2 + 72 strenght from talent = 760ap + 156ap = 916 ap or raw 760ap w/o counting talent. So final message - DON'T GEAR UP MORE THEN 80% OF ARP(GEM IN STRENGHT OR AGI) AND DEMAND BOTH AS RAID LEADERS AND RAID NONLEADING MEMBERS FROM WARIOR/WARIORS 1ST SINCE THEY (ONE WARIOR IS EASIER TO MANAGE TO KEEP SUNDERS) LOSE LESS DMG THROUGH IT AND IF NO WARIORS FROM ROGUE/ROGUES TO KEEP THEIR ARMOR REDUCTION DEBUFF !
