Warrior Titan in end game feel absolutely awful

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.

Every build feels awful on later maps (T10+) because GGG just increased the damage of mobs and called it a day.

I don't think they even intend for players to reach this height, it feels forgotten somehow.

You can't really do anything but dodge, and dodging is absolutely miserable in this game (iframes are shit, the speed is sometimes too slow, recovery frames lock you into animation for 0.1 seconds, etc.)

It feels they WANT us to rely on Dodge, but they forgot to make Dodge actually useful.
