One option that was floated (repeatedly) ages ago was to allow popups for those who want them, and just auto-everything-else for those who don't. I would be happy with that - and I don't think it would involve much work. So, having to click on something may slow down combat by a whisker, who cares? Seriously, if you don't want to make a decision, then just turn out auto-decide. Done. The issue with combat speed up to now has been painfully slow AI and slow/wasteful animations. Fix those, and I doubt people will worry about an extra click or two (and if they do, they can use the auto-decide option).
