The only thing I find annoying about DRG is the mandatory positional attacks. Boss turns to do something or adds running wild. Your HT may not connect. Gotta keep trying for that 15% damage buff. Your ID may not connect. Gotta keep trying to get Disembowel and Chaos Thrust up. But it's hard to say that they should change that aspect as it's one of the things that differentiates DRG from MNK.
