Did fistule in about 3 days, and bukhis spread out over a month. My ls has 4 dedicated members and 3-4 part timers (military/reserve) so we're very low man. This is our second Emp (first was Twashtar). Doing H2H and GA next for the other members.
With Razed Ruin/gh/scorp, whm is a beastly DD given that hexa is a crit ws. Here's a screenshot of Dagan and some Aftermath Numbers if you're interested. Mobs were T, no outside buffs, hexa was averaging 4k.
While you can get good hexa strikes (though you can do that with any decent club) and you can get some nice aftermath effects... you pretty much have to chose. Plus dagan doesn't do any dmg
