Have to disagree about provoke. Secondary is Traps. Provoke isn't necessary when you have Seeker Drones. Fire them off, they take the alpha which allows you to walk up and drop Poison Trap with the Field following you. Drop Acid Mortar, then Web Envelope everything (or just start with Web Envelope which will make them aggroed also) and the fire patches from your pyro will deal their full damage since they can't run away. I thought a single Run Speed IO basically maxed out SS by the way, since it has a cap. I can't imagine wasting 2 more slots on a movement speed that is capped, plus some people skip movement powers entirely for temp movement powers or even Ninja/Beast Run.
