First, Void Assassin. You have to main it to even be able to use it properly, As voidveil is locked behind that [main class only] barrier.
http://prntscr.com/j61685 For reference.
This cuts down on its uses and versatility. I had an interesting build with it, But it was swiftly eliminated when i saw this.
This is the only class like this, where one of its main features is locked like this.
Kensei, DH, Mages, Archers, Monks, Basically everything else doesnt and only a few skills are locked like that, But they can still work as sub classes, This is not true with VA. Enough about this...

My second complaint, DH has cobra and the only ways around are having high skill or multi hits, It makes certain bosses a joke.
It has very few rival builds as it can dodge what normally cant be. It's stupidly OP even when compared to Iesep body, That has to be reapplied every round or so, But not cobra as it reapplies automatically.
I personally think this can be remedied if every class had at least 1 Multihit skill, But those are rare skills.
All mage skills are single hit, So Cobra'd. Duelist/Kensei, Cobra'd. Unless you're a soldier using a spear or axe, or a gunner or even a rogue with dagger dance, There are very few ways around this other than move/attack, or absurdly high hit/autos.
I've seen to many meta builds with DH in it.
