And the last question, how much is population and is it much?
If youre into pvp. Dont give this game a try. Its one of the worst.
If youre into having 1 aim, which is farming gear, which means doing instances over and over and over and over and over, then give this game a try. After that, it means for you doing nothing. You already cleared the game when you got max lvl. Theres nothing else to do.
Dont expect open world activity. Its dead there. Doesnt exist. Game is fully instanced in end game.
-> Like mindless gear grind in scripted instances? Play it. It will 100% satisfy you
-> Like to do anything else than the above one? Dont even try. Theres nothing else to do
