If I had to pick one bug that tilts me off the face of the earth...

When you make a great escape from an enemy champion with just a sliver of health, usually less than 100hp ( Try to be about 10 hp or lower after a trade to recreate the bug), and about 3 to 7 seconds later you die. Red buff? no. Deathfire touch? no. Liandry's then? nope. Elder? Of course not. Oh, maybe it was duskblade, or minions? Aha, no. This took place in the jungle, twice as i recall it, and there were no monsters aggro'd to attack my champion, both times. So what could it have been? Unless Xin Zhao and then some other champions just kinda recieved DoT without any heads up, irdfk. It wasn't a bleed from a death's dance either. There was literally no reason in sight, and the enemy Xin Zhao didn't know what it was either.

You could theorize it's a sort of "lag" (Not regarding the other players ping and fps, mine were just fine the few times this occured) in which the game takes a few seconds to do the math and realise "Oh, he should've died there" and just kinda screws you last second? Is that not a bug?

And no, it wasn't a teemo cloaked with a sunfire cape, either. xD
