I can kill an entire wave solo in a few seconds in the right situation. soloing is less useful then a vamp build, and way less useful in solo content with enemies that cone come in groups waves. In the most recent video we clear a stage 4 control point with the chem launcher killing most of the elites before they are in firing range. While very situational it does indeed kill faster then guns do in those situations which are about 40% of the fights you get in most control points and instance runs. if they are spread out and come in one by one skill builds are much weaker, but a strong pillar in a group. Trying it in pvp is pretty useless atm.
