New player, server confusion
Try guesting on all the servers that interest you. Talk to people, make new friends and then transfer if you find your perfect server.
Unless you are very much into WvWvW, your home server doesn’t matter much since you can play on any two other servers in your region per day. The next day you get to choose new ones to guest or the same ones, if you liked it there.
I can say that Jade Quarry and Blackgate are very populated, where Tarnished Coast and blackgate are often full, Jade Quarry is more balanced and available. If you want to be part of this community to WvW one day, just delete your chracters which are probably not very high yet anyways. If you have no interest and you’re sure you never will, just guest.
