2h warriors were OP is D:OS 1 too having crazy damage output. Here it's just more silly.
The game is not about feeling "awesome" as you one click explode enemies into bloody bits. It's supposed to provide tactical challenge.
There's zero challenge in the game with the current state of some warfare abilities and 2h damage scaling. 2h/dw are also so much better than 1h or 1h + shield it's not even funny.
Warrior abilities need very severe nerfs to make the game actually interesting if you use them.
Several mage skills are OP too, but it's a separate topic.
I do feel like 2h is a little too strong in general, but both games pretty obviously make no attempt to present a well balanced experience. If you want such an experience then you can simply avoid skills you think are too powerful and crank the difficulty up a bit. I say this with the best of intent, not to be insulting. The system is just too complex with how much control the players and monsters have over the battlefield to really give any semblance of a fine tuned experience. if that's the experience you want you will almost certainly have to force the games hand.
