I've played this game for a while now. And I keep on seeing people that say: Oh I don't do much dps, I play support/tank!
I don't bash people for it, I mean I can do Torment IV by myself and thuscan carry those players in torments below IV. So I don't bother much.
But once in a while I ask them why they play that role? I mean sure I have a "taunt" as a Crusader and use "taunt" to up keep my wizard buddy safe. Any good player with such an ability included in his spec would. Am I suddenly a tank? I make my spec and built so that I can maximise my dps first and survival second. Though I might change that a little towards Torment VI.
My opinion is that these players who claim these things are either 2 things:
1. they want to play that particular role, because they like it - even though there isn't any real reason to do so
2. they want to play that particular role, because they suck at playing this game and therefore can "get away with it" if they claim they play tank/support.
If you then check how they did their gear, it is madness mostly. So I am going for the most part with option 2 here. Again I don't mind as I can clear everything fast enough. I don't expect "pro" players to show up in a random group. I am in those group mainly because it is more fun to play with multiple people. So it is fine. I just don't get that mentality. I mean it is far better to maximise your dps first. If you maximise your survival/support first, you'll be taking a LONG LONG time before anything gets downed = less survivability actually. The longer it takes the more chance you have to fail.
