So after beating Path of fire on my guardian I got really bored of him. I wanted to start a thief but always hear how bad they are at PvE stuff like raids or fracs. so I picked a Guard and I just fall asleep playing him. thinking of starting a thief but I don't want to get kicked from groups for not being "meta" and I don't have my own guild. I don't know what to do can I get some advice?
