I am on Crystal Desert [US], and during our big NA fights and Early AU, I notice the game starting to rubber band(aka you cant use skills properly, move, etc.) We will usually get into about 3 or so fights until it properly spikes to the point of not being able to play.
Average fight in #’s for NA Primetime:
-80+ on a busy night
-50-60 with guild fights in smc
100+ With all 3 servers last matchup HoD/EBAY/CD
^Was barely playable on EB
