[Foxplay]

Played and raided with most classes (see sig)

If you want to warm body and never be asked to do anything other than the occasional CR / body dragging I would say rogue....

Wizard is a great choice as well but there is a lot of things wizard can do that rogue cannot that goes beyond the "warm body" descriptor... Wizards can help move people around for different targets / windows which that alone is a lot more time and "involvement" than your typical rogue log in, auto attack backstab... they can aggro kite better than any other class

Rogue is always in higher demand than wizard, simply because melee dps takes center spotlight in velious (unless you are extreme wizard stacking with guild bots... but at that point the same amount of rogues are probably going to have a similar effect in plastering the boss into oblivion anyway)

At that point it becomes what are your gearing and goals outside of just warm body raiding.... a Rogue cant really do much on their own even with extremely good gear their solo play is laughable compared to other classes. Even for small man plat farms most teams will just bring a monk/enc/shm or cleric. Wizard can solo decently, Rend robe, epic, and Manna Robe(or manastone for oldworld) and Wizard feels like a new class entirely (just root and click things to death) So long as they dont summon your gucci
