so im seeing a lot of angry dps here, some not, and most tanks i notice really dont care, same for most healers.
the argument that fights will be scaled around tank damage so tanks need dps gear is ridiculous, blizzard knows that, and they will scale it around what tanks CAN do with tank gear, so thats 2% AP of all physical damage, wich indeed comes from base physical damage for 20S (unchanged by armor/dodge/parry/block/shields) so if the boss does more damage because the healers are getting better, the tanks will obviously do more damage as well, more AoE damage means boss does less single target, its always worked that way.
also, compared to vengeance, dps gear boosting us makes like 5% difference, we could barely do more since our mechanic works around LOADS of AP and stacking STR gems is worthless compared to vengeance right now, crit and haste wouldnt matter much either, because wou could maybe max crit to 10-12% out of a basic 5% and haste is useless for people with 0 casting time nor CDs save for a few basic abilities (like crusader strike), only attack speed on our weapon swings would change, and our white hits are s**t
DPS still do the same thing they always do, now they just have someone else contending for top DPS, wich tanks still dont care about when trying to survive in a raid.
problem is, these DPS cant take it when someone from another department comes along, and does their job better than them, so basically, egohurt.
what they cant seem to understand is the fact that they are very well capable of doing it better still, if only theyd spend a little more time on their job.
healers are still doing their best to keep the raid alive, and still have to focus on tanks, because our self healing/active mitigation is a fraction of the actual incoming damage, without healers, tanks still die.
so yeah, the tank role has been expanded, still remains that tanks try to stay alive and get the damage on themselves whilst being a bit more useful.
personally, I play as a pala tank, and yes questing is horrible, but in dungeons and raids i am more capable of assisting healers and dps than ever, and what do the dps do? they get mad because DPS is still DPS and tank is now also DPS. coming with arguments what if every dps could tank? well? thats a completely crooked comparison, since as far as i know (without facts) the lowest percentage of players are tanks, then come healers and the highest part is DPS, so, blizzard gives the lowest percentage something to make them more useful (not perfectly with regards to questing) and you come with the argument that the most people in the game should then also be capable of the most roles-in-one? I think you are most certainly mistaken.
and about healers and more roles, if none of you noticed, they are there, a good disco priest works wonders on elegon, and afaik so do mistweavers
