I had figured that the difference flavors of convienance would be other deciding factors for what makes people pick certain classes, here are my ideas.
Rogues - mentioned in my rogues-sprint thread. A used ability that builds up speed to a certain point and stays active until you engage in combat, long cooldown.
Warriors - a passive skill that increases your movespeed for running towards an enemy, enticing you to slaughter everything on your way to your destination.
Mages - Teleports or cheap to cast blinking.
Clerics - a cheap to cast movespeed spell that effects that whole party, or a stacking passive buff that increases with enemy slain that lasts for 15 seconds or so.
