The annoying part will be trying to keep up Blood of the dragon to keep doing Geirskoguls during aoe phases, and if Geiskogul's damage will even be comparable to our DS spam. In other words, if it takes 2-3 full thrust or CT combos to rack up enough duration to use Geirskogul without losing our stance, then Geirskogul will need to he extremely powerful to make up the loss of 4-8 Doom Spikes. I suppose a work around would be to build up the stande duration before the AoE phase, burn geirskogul when adds pop, then resume your normal aoe rotation, and hope blood of the dragon cool down is up before the last mob is dead so you can start building it back up. Losing the stance may suck between running between mobs if the initial duration is low—which they said it would be(and that geirskogul would subtract more than the max initial duration".
