I agree, mostly. And it's even a lot worse with for example summoning.
Summoning is really weak, for various reasons I stated long ago, and at best has a role as a small addon to other skills. Sadly even this role it cannot fulfill for the here stated reason of the missing possibility to combine stuff properly.
Right now hybrids only work for completely static skills, like teleport or adrenaline for example.

Really wish Larian would attend to all this stuff...


Think for yourself! Or others will do it...
