No to upgrading armour etc system. That's not what KAG is about. Vaulting is not being removed, but is getting changed a little with corner kicking. We'll be getting all of that tweaked out with the testers so that movement is still both simple and fairly deep. I _do_ want to cut down on the amount of "hold WD to get to battlefield" though. Slash vaulting will likely stay as it lets knights get out of smaller pits without a builder as well.
