I like having all the abilities so far. The combat does seem overwhelming right now for me personally, because I'm not sure when how recovery time is working right now. I've seen mention of auto-attack not working properly which I imagine is making it much harder to get a proper sense of what is going on. But I've told party members to do things, seen that little recovery bar going down and then not do anything until I give them a new order.
Another big difference from BG is the lack of AI scripts. I have no idea if they intend to include them or something like them, but at the very least in BG you could trust character you left untouched to attack something.
If we can get combat to be less confusing, I think asking about the number of abilities would be more appropriate then.
