More specifically, team fight ranked. As far as I know, the only way to get into a match, is to set the search to 'Worldwide". I'm on the east coast in the US, and the matches are non existent. If I get desperate I will set to world wide, but the ping is unstable. 150ms to 300ms.
So ya, that's a major problem. It's ranked, and I already have a major disadvantage.
TBH, I don't know much about the server side of things. Is there no way to be world wide without such an outrageous ping? Id imagine it's a matter of cost, but without any players to play against in your region, pretty much renders the mode useless.
It is my favorite mode on the game. I think if higher skilled players had a place to go, like ranked or something else you could imagine, maybe it would have balanced out the servers more to the point where a novice server wasn't needed.
