Dark Knight is more of a magic tank with their AOE now being a magic defense up.

Paladin has a different gauge that let's them do different things than warriors.
Warriors is different than Dark knight.
Dark Knight is different from gunbreaker.

Yes, they have tools to mitigate damage, wow, so bad.
But Paladin has a heal, warrior has fell cleave, Gunbreaker gets a regen and Dark knight has... TBN i guess?

Their "Invulns" are completely different too. They all do the "same" thing but Dark knights is absolute garbage and Warrior can't even move.

And why ARE GAP CLOSERS A BAD THING??
They are absolutely not! YOu don't want to be that tank that has to make the add move to you because you slowly have to run up to them again after a pushback, they forcefully move somewhere etc. And Paladin was said tank, it's... really lame to run after Bosses just because you can't get close again fast.

I don't think Tanks have the worst thing going on with that.
