The west coast could use a server, but honestly I don't like that there was community and NA official as it was. We only need 1 server, we can't even get it full to 140 at peak hours, so why would we need 3 NA battle servers?
One is enough, the official servers are fine, and the maps are edited/removed based on feedback, and are continually being added. I'd rather not split the battle community into west vs east coast, or we're only going to have 80 people tops in either server at peak times...I'm all about more people playing at once.
Some of the random plains and steppe maps on NA1 yesterday were some of the most epic displays of teamwork I've seen in a long time.
