It's probably too late to say this, but I hope there is an option for switching combats to RTwP mode.
I'm not a fan of turn-based combats and I think it's less realistic because combats in real life never are turn-based. It serves no purpose other than making you feel like it's a tabletop game and slowering down the pace of combats. While tabletop games undoubtedly need it, computer games are well-capable of handling RTwP combats and do not need to stick to turn-based combats.
It does serve a purpose, a fairly major one. There is a not-insubstantial number of people like me who hate realtime combat. I can't play them, I'm not fast enough to process everything and I like being methodical and considered in how I use my abilities as a reaction to having the time to see what enemies do. Like chess for example. This game would probably be unplayable for me if it was not turn based. (It was actually the deciding factor in me making the purchase.) Even RTwP games, while better, are still vexing. It's a VERY different experience than turn based, and one I personally think is worse, since I can't react as well to things.
That said, yes, enemy turns take needlessly long, probably because it's EA and it will almost certainly get better.
