I started playing on the highest population EU, English, PVP server during head-start, now during the day there is nobody else online in my guild of over 100+ people, when I join a battleground it ends shortly after starting because of not enough players, there are less than 20 people on fleet and 2-3 people on each planet.
An MMO this is not. it's an RPG with online functionality, and if you're happy to pay monthy for such a service, so be it.
