Looking for some insight on wizard

[FlipisWin]

Got a friend rolling a wizzy tomorrow, any insight on the general life of a wizard? After reading through the forums, I feel inclined to tell him to steer clear of the class. But then others say its not that bad, just gotta get to where you raid. So is this guy who will be starting from scratch, be shooting himself in the foot by playing a wizzy? He enjoys grouping, but our play times are kinda jacked atm so he might get stuck going solo. Is it all that terrible to solo as a wizzy?

Guess in a nut shell, could some of you elder wizards throw me some pros and cons from your own personal experience?
