Update: It seems the max range has been fixed to 60y

I died twice due to the Stinging Swarm ability. I Google about the ability, and many people seem to have issues surviving it since it doesn't seem to have a range limit. Because of this, many were reporting the ability as bugged. I suppose that as a DPS class, this would be a bit harder than it would be as a tank. Anyway, I'm leaving this here in case anyone finds it useful.
