Some of you guys have terrible math when it comes to rotations. I've already addressed this in a previous post, but if you are going by theoretical max dps for a summoner single target, you have to realize the following:
1.) You only get 24 abilities per minute minus fester/energy drain for damage.
2.) Minus contagion which I think is highly overrated on this board (none the less useful), you are spending 10-12 of those actions per minute refreshing dots, so you have generally around 12 actions per minute to do whatever you want, minus any time spent by moving around or avoiding things.
