Hybrid builds aren't mean to work. You can only acquire so many stats and you're meant to specialize in certain trees and abilities that have synergy with eachother.
There's a reason you have a party of 4. Instead of having every member be a hybrid, you specialize roles so that your party itself is hybrid and versatile. I'm completely fine with that.
From a fantasy perspective I love the idea of a battlemage, but from a gameplay perspective it makes complete sense why it's not a powerful option in a game like this. Though, for the record, it CAN work, it's just far from optimal.
