Well for me, I have yet to play a game with TB combat that was any good. So literally anything that makes the combat go faster in a TB system is a very good thing for me. I would even support having an auto-resolve combat option available to be able to bypass combat. The best option of course would be to have in-game options for resolving encounters without combat. If that were possible for every single combat encounter, that would be ideal.
As for your specific concern, I agree with it in principle, but the devs have said the way they intend to get around that is to have enemies widely dispersed and far away at the beginning of combat so neither side can immediately attack anybody right away.
