Why can't NA have 2 servers?
One west, one east. You can pick which server to play on right after you log in. West gets good ping, East gets good ping, Central gets acceptable ping, no need to make a new account or to port it over. Profit? I swear almost every mainstream game has this (WoW, DOTA 2, CSGO, etc) Plus you wont have pro players angry that they have 60 ping instead of the 10 they had before with this upcoming server move.
