The server seems very stable now, after all the crashes during head start.
There are a lot of people capped out at max level already, 5-6 days into release, and apparently zero content for any of them to complete. Most people will be maxed by the end of the month. It is an easy game.
There are rumours there will be a lot of microtransactions in the game. Pay a subscription fee and then ask people to pay more and more money for "extra" options like new races and such. I won't be buying anything like that.
