Guild Wars 2

I play on a NA server, since I live in South America, and I have friends who play with me, but, during my long time playing GW1, I’ve met some nice folks from europe, and it saddens me not being able to play with them as well. So, why can’t someone from a NA server guest to an EU one?

Arenanet talked about this and they said it just isn’t feasable to do, cause to much trouble with performance.
