Heh, I thought you already knew that

Success is mostly about squeezing the biggest DPS out of your PSI. That typically means maximising damage (and top gear) for high-boosted defenders, and building skills so that debuffs that are not based on damage are given to low-level ill-equipped defenders. A berzerker worth 25 or 75 PSI can set enemies bleeding 60% just as well as anybody else. A 60 PSI ice mage will be casting ONLY his freeze+chill-enhanced ice ball like there's no tomorrow. And neither needs a good weapon to do so. The guy that has been boosted with 600 PSI and waves a +40 unique sword, that's the person to hit the bleeding frozen enemy with maximum power.
4 archers boosted to the roof pack a tremendous firepower - as long as their targets are stripped of armor and bleeding.
