My play group is starting to get into the game, and there is a weird rule I cant wrap my brain around. If you are Taken out, do you still get to change stances when it comes time for your heroic spirit turn? It seems weird that you could swap into bleeding/ Zombie and just negate threat by damage that way.

Even more so when something like Angel/ Cavalry  doesn't have access to that . 

Is there some kind of vulnerability I am not seeing here?
