Agreed, I much prefer selectable formations the same as in the old Infinity engine games, that have been emulated in the newer CRPGs, I think it worked really well in them and with a little tweaking could probably service this game quite nicely. and yes I find Larians way rather confusing and unintuitive in comparison.
I haven't had chance to put much time into it yet so I don't know if their system will grow on me but I don't think so, I found a top down view to play the game (though I don't remember how) so why not give us classic controls with the classic view?
I can't speak for you, but I can tell you that if anything over the years using it since DOS1 I've grown more and more annoyed about it. There's no "getting use to it". But even if that happened somehow, would be the gaming equivalent of growing accustomed to an abusive relationship.
