To play a Tank or not?

[Yak]

I am having a blast playing my Mag but I also want to have an ALT and try out other classes as part of the fun.

I am torn between a Warrior, Pally and SK. Maybe a Cleric as well. I think it would be fun and challenging to be a tank. It always seems to be a much needed class for RAIDS. Also, if anyone had any starter gear for a tank, I promise that they would get a return on their investment me as a player. Otherwise making a Warrior with out starter gear is suicide is not?
