An instanced run for a tank, teaching them the fundamentals of grabbing and maintaining enmity. It also would be nice if it were designed to stop speed-running by making enmity slowly reduce over time; so if you try to pull everything to one spot then the enemies would stop following you and start attacking the NPCs aiding you, resulting in a fail.

I am sick of being forced to do these speed runs with tanks who just can not tank. Please introduce an instanced battle to train tanks .
