There is a huge difference between 0 ping and 35 ping though, particularly in pro-level LoL. It is strategic but that ping can be the difference between flashing a skillshot or not, and swinging the whole course of a teamfight.

Of course 35 ping is not THAT bad and I agree, while unfair, it wouldnt be the end of the world, it's not even Worlds, just MSI, an invitational event.
