Yeah, If you're not using the mechanics the game gives you, you're only limiting yourself, and if you're doing that then it's your fault, not the game dificulty. The Magic resist bar is there with the sole intention of blocking CC. If you can break that and permacc someone before killing, then you did great. That's no flaw, that's the way it is, and if you're going around that and avoiding using CC on them that's just artificial dificulty, much like playing dark souls bare handed or something.

I have to agree that there are some stuff way too overpowered at the moment though, like Warlord and Rage, but they are what they are, and if not that there would be another way to build to be strong too. I've breezed through DOSEE Tactician and I'm anciously waiting for that mode on DOS2 as well, because that sure is gonna be harder than the first game.
