Tank classes are balanced quite well.

Warrior most offensiv tank -> then Darkknight -> then Paladin as most defensive Tank.

I like to play every Tank, doesn't matter if dailys, primals or alex. All 3 have their own gameplay, style and tankyness.
Pls don't always change the classes. Atm it's balanced extremly well !
If a paladin would do the same amount of damage as a warrior, it would be really unbalanced cause a warrior doesnt have that much defensive cooldowns.
I really don't see the problem. You want to do a lot of damage -> play Warrior. You want more tankyness but lack a bit of damage -> play paladin.

But it looks like you as a main paladin want to be tanky af and on place nr.1 in dps... that doesnt work out dude
