Shoots into a clusterfuck, hit the only ally.

This happened to me so many times... what's funny, is that the awesome melee ally in the middle will report you, since he definitely had a chance to survive, and kill them all.
I believe you still forget a few, but i don't know how to meme, not my generation :
Dehorse an ennemy cav coming from the back,
get raped in melee by it, since all your allies are charging and didn't notice it.
Dehorse an ennemy cav very close to you,
get teamkilled by melee ally.
Succesfully hit an ennemy engaging an ally three successive times,
watch the ally continuing his journey, and leaving you alone. To die by cav/ninjas.
