Yeah, Shadowbite made everyone think we were getting an AoE dot. Misleading name AND animation. I honestly think the developers were going to make it an AoE dot at one point, but changed their minds after designing all of the passives. Because let's face it, our AoE would have been completely unrivaled this expansion with all of these passives, Apex Arrow, and an AoE dot on top of that.
That said, I find the Stormbite/Caustic Bite -> Refulgent Arrow passive awkward as hell. I feel as if we need an AoE version of Straight Shot/Refulgent Arrow somewhere, because you're going to be casting those dots during large pulls in dungeons, and we're literally going to have a bunch of unused Refulgent procs because using it in multi-target fights is a straight up DPS loss. It'd be a good excuse to bring Wide Volley back into the game...
