While leveling solo i’ve gone Dual Axes + Longbow with the standard Signet leveling build. and Axe #5 is fantastic.
I’ll pull as many mobs as i can to stack, Drop the longbow Burst on them, followed by Longbow #3 for might stacks, switch to axes and pop #5, I am now hitting every single mob both with the Axe and with the burning effect due to the whirl finisher. By the time #5 stops everything is dead. In fact even with something like 7+ mobs where I might get downed, I would instantly rally because of the burn inflicted via combo field.
Combined with the ability to move while attacking, and more importantly the ability to dodge while attacking, its actually very useful!
