hmm, stalkers are fun to play, but theyre pretty hard to solo level... pali/lk get invite because theyre such pro tanks, but they can be hard to train if youre not sure how to use them. Priests are fun to use, easy to train, theyre pretty much sp oriented though, and they get party invites because every group needs a healer =D. only other option id say would be to roll champ, because theyre not totally sp oriented, theyre fairly easy to level (if you healbomb) and they can serve as good healers and theyre fun to play.
