Thanks for the response. I'm fine with ability pruning as long as gameplay is still fun. Wildstar and TESO are the recent MMOs I have played that restrict the number of abilities you can slot. They have also tried to make MMO combat more action based. TESO only allows 6 skills per action bar (12 total with weapon swap) while Wildstar gives you 8. Combat in both TESO and Wildstar have mobs throwing out a lot of telegraphs with Wildstar punishing you the most if you don't avoid the telegraph.
Based off what you are saying about fight mechanics getting more complex with lots of movement, do you foresee gameplay in WoD becoming more action-based similar to Wildstar (but not as punishing/difficult).
WoW and D3 have always borrowed ideas back and forth, and D3 has the limited loadout too - so I think the WoW team is trying to get the advantages of that, but without doing it directly. I don't see them ever doing that explicitly, but once they pare down most classes to 4-5 "main" buttons plus a few random things, they'll have achieved that. They can't stop people from hotbarring all their favorite mounts or whatever, but their main action buttons will probably be similar.
I don't think they'll ever go full-on Wildstar telegraph, but I still consider WoW the grandfather of "dodge the floor" style combat. Having returned recently for the end of MoP, last time I played was early Cata, I see the increase in boss complexity pretty obvious. There's always fights in every raid tier that are tougher/easier than others, but even some of the dungeon heroics have pretty involved mechanics (of course we can just outgear them now). A lot of multiple phases based on health %, or "repeat these 2-3 phases over and over", dodging the floor, interrupting the boss, watching for adds, etc. None of these are new to WoW by a long-shot, but it seems like more and more often you're getting multiple of those things at the same time. Which again, personally, I find much more valuable than complex rotations.
As a shadow priest, I'm looking really forward to the dot/haste changes. No more "snapshotting", no more haste breakpoints. No more hit too! Reading over some of the changes though, it seems like shadow priest just had some "buttons I really never press" and "buttons I always press once when I log in then leave it up forever" removed. I don't think our "main" rotation has changed too much (not that dot classes have a rotation, just our priority), but there's some interesting talents that could change things up a lot. And our mastery is all about single-target nuke DPS (which seems really dumb for something called "mastery" with us being a dot class). I get the feeling the changes for my class will end up with us having a few different rotations/priorities depending on the fight, which could be a interesting level of complexity (do I dot these guys up? Go single target? do I save orbs for X, or use them now? etc).
From the bitching though, it sounds like other classes had straight up every day rotation skills axed. I can't speak to that.
