Do you imagine what does it mean to be a stealther? You waiting hours for any kind of actions, then you find anything to kill and get perhaps an add. OK, you vanish and what now? You will wait and search for actions another hour.
Or you just place you toon somewhere in NF close to level spots and have a fun killing greys and greens soloes.
On this server rules the zerg. And this game is an MMO, a social game, just roll a group class and have a fun together with you group, your guild mates, with your zerg .
