I had a few reasons. Skill up weapon for later dates, possible SEBW zerging, and as the main weapon for a good atma/gear build for Infernal Scythe, Endark is also boosted to 70+ a whack, too. WSing and having enough TP to WS again after 1 round isn't impossible, either. Sure, a near-guaranteed 2k+ WS might not be the epeen of other crit-fueled ventures, but the speed you can crank them out counts. Herc Slash is the better WS, sure, and I wouldn't be surprised if those people also had PLD on the side, but I haven't jumped toward that trial if only because I'm not looking forward to mass amounts of gnats and ladybugs. Someday. Maybe. x.x
