I mean a lot of people in NA just live east coast. They have better internet and their location is better for an EU server. That's just the way it is. As Godfreid said, we could do it on a west coast server if we really wanted to but we aren't trying to scumbag anyone. Regardless, the 5 rounds on EU are to the EU team's advantage. They had about half the ping if not more than the NA team and just couldn't win the rounds. I'm sure when NA team starts fighting france, germany, uk who have avg better ping then spain (and if anything have better ping on EU than NAs get on NA, especially the french) you won't be complaining about how much of an advantage we have.
We now have a New York server available which should actually give most EU's better ping on NA than most NA's will have on EU.
NAs are just better and have better internet to handle switching to EU
