Randomized positionals, where we have no idea in advance where we even need to be at the end of a combo is asinine. If positionals MUST be used, and i fail to see why in the first place as no ranged, caster, or tank job has to deal with them, at least make it predictable, such as say, wheeling thrust is proc'd after chaos, and fang and claw is proc'd after full thrust.
I have to say though the biggest flaw is in how Geirskogul is designed, for something SE claimed would be our big finisher, we got a 200 potency leg sweep? It's absurdly weak for all of the build up and maintenance it requires to even use. And if you are using the rotation as many i have read advised, blood will always be on cooldown so heaven help you in any fight where the boss becomes untargetable for more than a few seconds, which most bosses i can think of do at some point or another.
