Which classes can attack during/contrl DR and DEF UP?

i disagree about DR being short, empress casts her every 80 secs for 20 secs, that means that you're losing 1/4 of the time you have to attack. and let's not go into PB.

But that's if you're soloing or aren't a class with bind/crash and i don't think the op wants either of those things.
