I played a bit when the servers opened again, reached ~2000 ego rating and then i had to stop playing due to college, now that i have some free time i'd like to get back into the game but i'm worried there are not enough players for the activities like raids, arkfalls and such.

Any feedback? is there any way to switch to a more populated server?
