I have no problem with adapting. There is a point though that it becomes completely unfun and you have to accpet that the class needs some major improvements. If you want to have a shot at playing a warrior, you have to have a healer attached to you hip at all times. The best way to do this is to go FC, but, that's not really a great roll for warriors since they were stripped of all their utility and pushed into a burst dps roll, which was recently nerfed.
The only viable spec for overall utility is Fury because it's the only way to get a snare. 1h/shield fury is almost playable, but, still very gimp. You negate your own talent tree benefits just to be almost playable. Protection is a nice health boost and some decent talents but you're pretty much unable to support your healer and once they drop, your done for. Arms is kind of an all or nothing spec and if you can get a charge, you might get lucky with your rng. Something that inconsistant really isn't benefit to any team.
You can't maintain any ToT unless you spec Fury. Even then you're pretty much reduced to walking up to everything and trying to hit it, because every ranged class has a 40 yard spell that will put you into combat, taking away your only distance closer and your primary source of rage generation. There are things you can get away with in duels or simulated arenas, but, there are plenty better options. On their own, warriors are garbage and ultimately not worth a spot in a premade since other classes bring more utility and you don't have to babysit them.
None of that means that I'm going to stop playing my warrior. Trying to pass them off as something other than the worst class in the bracket by far is downright insulting.
