The one thing that has confused me on these changes so far was that despite blizzard saying they are doing away with armour pen because it makes itemisation and dps predictions alot more complicated . Why does the arms tree on warriors have ArP as part of it's mastery still ? Will frost get any sort of talents to reduce armour too or will our dps fluctuate massively due to having up to 50% and 60% differences on how much armour each boss/player/mob has ? Also Outbreak is supposedly going to help us when target switching or when disease's get dispelled but with alot slower rune charging it puts us back to square 1 .
Also making a rotation simpler and slower makes it alot more boring and alot less about skill and timming . All through WOTLK they have been pushing at us the theory that the more complex and active the rotation the more enjoyable and skill reliant it is but now they seem to be going back to square 1 again.
Pretty sure I will be pleasantly suprised and my fears will prove unfounded once we see it in action , although on paper it seems they have gone back on all they have said.
