Brand New. Which class?

[Flashback]

Hello everyone. I just got a copy of Titanium and fired it up on project 1999. I cannot make up my mind on what class to play. I assume that the popular classes for new players is fully saturated on the server. So what class is more rare 50+ and has a good place in groups and is able to do the solo gig? I'm leaning toward wizard but really have a desire to Ikky SK. Can I enjoy the game here non twink as an sk? i've read a lot of posts and see that the server is bloated with twinks. What do you think. wizardo or lizardo?
