On all 2 Handers, there's basically nothing better for DD than

VV/RR/Apoc

With Caladbolg DRKs being an exception.

This is particularly useful for DRG because of Drakesbane, being high STR mod, a crit WS, and everything is sexy with apoc.

It provides easy TP building with VV, and allows a lot of ways to go around the high stp cost of a 5hit, along with capped fSTR and DA to boot. RR provides huge spike crits and high crit rate, along with capped dDEX. Apoc gives Reraise III along with probably the best TP atma (TA +15%) AND gives you HUGE spikes on your WS's (Apoc is the reason you see 6k Ascetic Fury and 8k Ukko's Fury and the like).
