Warrior Titan feels absolutely awful in end game

I'm trying to do end game maps 10+. I have 3000 hp, 40% block chance, 80% armor damage reduction, 78-78-78 resistance, and I still get one shot by absolutely everything. Every single attack has a VERY long animation with the Titan and it's almost impossible to avoid getting hit. Whats the point of a heavy, slow, tanky character that still get one shot extremely easily, no matter what. I feel like Warrior should either get 50% damage reduction while in an animation (in the passive skill tree) or make animation faster because this almost unplayable in the end game.
