Playstyle Question Advice Please

[Curmudgen]

Ok I got my titanium discs in the mail today and will be setting up soon. I have a question for server folks.

When I play, the time will be from 9-11:00 cst max, so 2 hours at most. With such a limited play time, what do ya think would be a viable character?

I guess being a porting class like wizard or Druid would help with short play times?

I have played necromancer on live to 70 and I do like the class so I know that is a good choice for if my limited playtime means mostly solo.

I was though interested in a few other classes. Can a shadowknight solo much through all levels? How about a ranger? I am not too interested in Mage.

Can being a porting class like Druid or Wizard be good for short playtimes? Never played either but I thought wizards were wanted for the boom boom.

The other question is are two hours a night doable as a group dependent class? I have no RL friends playing with me and I know no one on the server. I played a monk for awhile solo early live but it was way slow. I have wondered about rogue but it is totally group dependent.

So lots of questions. Any comments? I have never played shaman before, so wonder if that is an option for solo or short duration player?
