Berserk, Souleater, and Double Attack do work very nicely together..Above is a nice DA proc, though I'm sure DRK can reach much higher numbers. Didn't have an HP build and my STR gear is quite sub par. Not to mention, NQ behe is very weak too lol.
However I'd like to see those kinds of numbers from DRK/SAM. Like you mentioned, merit mobs die very quickly and I doubt a DRK will get very many scythe swings in one fight - even with a haste build. Sure it'd lose some dot without berserk...However that Brutal earring combined with Fighter's Roll could be pretty rewarding.
Brutal is 5% and subbing /war is 20% correct? Not sure how much Fighter's Roll adds but from my exp it procs a lot more often.
What it all comes down to, is who can spam those 1400-2000DMG WS fastest. Currently that leader is a DRK/NIN with Brutal earring/Klub or Ridill. Just like you mentioned^^;
That's why I bring up DRK/SAM, it'd be interesting if we can still pump 1400-2000 WS with that sub.
DRK/WAR are much more common to come across of course, so dealing 1400=>2400 WS(max?), the equipment to outparse them is very expensive and rare.
Merit Scythe DRK/WAR will only beat a Merit Axe DRK/NIN because of DoT, hence Kiiro's 2100 Rampage. Apparently can land those on Mamools as well, but haven't got any screenies of that yet.
Still interested in DRK/WAR vs DRK/NIN however, I think /NIN could possibly get TP a lot faster...Have you personally ever meritted with Kiiro before, Tyrath?
