Brd and mch is probably your best bet, iam not sure about rdm because just like melee class it has boring rotation.

All melee class in this game (rdm included) has "follow the trail" rotation set

Rdm rotation is basically fill your gauge by switching between black magic and white magic until both gauge reach 80 then charge in do 1-2-3 melee combo, jump back and finisher, repeat until dead. There is nothing more thats pretty much what you will do with your rdm when you reach 70
