I kinda agree with cokane, in the sense that I always build parties, not individual characters in these types of games, and tend to separate them to more passive auto-attack guys who do nothing else, and active ability-using characters who do that more than attacks. And I usually fill my parties with the passive types, with as little active types as possible.
I don't see a problem with games like PoE2 though, since you can pretty much let the AI do most of the talent usage, or just pick mostly passive talents. So I think these games cater easily to this type of playing, provided you're willing to learn and configure the AI.
