What is the method or strategy as far as how many people should active maintain stacks, and when should one let the stacks drop off. Currently we are letting 2 people gain stacks, and times letting one get to 20 stacks before reseting it, while the other one will drop at 10 stacks to avoid draining the healers. Do stacks even need to go to 20 or whats the most effective way of doing this.
