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

Off the top of my head...cannoneers, mechs, corsairs, kaiser, db, shadower, post red mm, current bm, all adv mages, AB after soul seeker fix, evan, merc, and probably more including zero.

Fyi: All summons ignore dr. Kaiser is the only class capable of bypassing for periods of time with his whole skill set. A few skills can bypass dr otherwise (mage auras i think, flame meggido, etc) but it isn't anywhere on that level of dps so.

I didn't know all of those classes hav moves that bypass damage reflect =0 Or are you just talking about summons? Because I didn't mean summons in my post =x
Sorta just wanted classes that can either control it [like magic crash hero and pali] or bypass it completely [demon slayer's dark meta and kaiser's transformation]

I don't see how bowmaster and mercedes aren't affected by damage reflect =0 Everytime i see them they seem to die quickly when DR activates lol

@Everyone else
Thanks so much for all the classes you guys listed~. I think I might be leaning towards hero and palidan. Palidan because i can just rip off the equips off my DS and Hero because i used to have one pre-bb in windia, and nostalgia would be nice [and i can rip off equips from my kaiser]
