[Gameplay] Ashe Runaan's Bug: The reason she's bad.
As you can see, runaans is not working properly on Ashe. Runaan's hurricane bolts are not firing any or more than one bolt from different ranges/angles (Usually max range results in no bolts firing, mid range results in 0 - 2 firing, melee fires 2).
Runaan's hurricane bolts do not proc Ashe's Q passive either (The stacks. They do proc the active part). I haven't done the math (and I don't plan to), but I wouldn't be surprised if the bolts didn't apply ashe's crit damage from her frostshot passive too.
I'm also not sure if this bug is exclusive to ashe, and people just haven't noticed it on other champions (Not the most popular item except on Kalista who is short range and probably wouldn't experience the bug anyway).
