NA player. I made smurfs for EUNE and EUW to play with overseas friends and my ping improved better.
In NA I get 100 constant pings with extremely often long ping spikes to 700-1000 that last entire games and massive 3000 spikes that last 3 seconds while I'm in a fight.
I was slightly lying when I said I get better ping when I meant I get better overall. On EU servers I get 125 constant ping, but no fucking ping spikes. Also a lot of my problems connecting to games went away.
