Could be a lot of work :P
But really, combat could still be made more dynamic. A cool reaction could be that you equip a melee weapon for 0 AP when an enemy gets near you if you have a bow equipped, though that'd only be worth it if bows had reduced accuracy or damage up close (which I think they perhaps should).
Cover should hopefully arrive still, though I'm surprised we haven't seen it. Didn't they show it in videos in the past? Seems like something that really needs to be integrated into every combat situation, so I'm a little nervous it might have been ditched since many combat encounters don't seem like they have any possible cover in them, though that obviously could change.
Characters or bosses getting turns every other character sounds really hard to balance. Maybe could work for a couple unique bosses.
Contingency skills would be cool, like if you're damaged by fire this turn, you instantly cast rain or something.
Dynamic reactions could definitely create a lot more room for making unique combats.
