Attacking supports != 1 v 1ing supports. You literally said this earlier, im quoting your entire post:

That's why I am so pissed. HE DOES NOT! Try that in lobby. BH vs Riki 1 v 1. Their stats are almost the same, but BH has crit every 1 second and damage bonus. If he gets MKB, you can forget about backstabbing him, and then you die. You must snowball with him, but since the diffusal nerf it is hard af to do versus a good team.

You compared two heroes in an only 1 v 1 scenario. That is not attacking a support and going for the backline in a teamfight. You literally call it a 1 v 1 and say that's a late game teamfight. You either have incredibly short term memory or you realized how dumb your idea of a teamfight was and decided to change it to agree with me.

Either way, thanks for proving my point that your original argument (you saying team fights are 1 v 1 duels) is completely retarded. Glad you could realize that after so many posts, though it should have been immediately clear.
