I think one of the problems with the game is actually that it tries to do so much that it leaves a lot of things much less polished than they should be.
I would rather that Larian work instead of adding new skill trees, to make the existing skills much more balanced and useful.
I totally agree with unlocking Talents for modding and also adding more Talents and rebalancing others, because Talents remain as underwhelming as they were in D:OS 1, with so much potential unfulfilled.
