You say air shifters are broken as is blindness traps. I tend to disagree because, quite frankly, air shifters have never ever ever bothered me except the fact that they can escape at a whim. In fact, they can just do fly, dodge like a mofo, and leave at their discretion. Kinda like how a trapper can drop a blindness trap and escape at their discretion. The only different is that a) for air shifters, you can limit this by malediction or earthbind and b) for trappers, you can limit this by cure blindness preps. In fact, it's easier for air shifters to escape than a trapper. You're argument is based on one class and cabal combo unable to do much, supposedly, against another class based on a niche set of situations because of how it was presented to you. You never argued that shifters need to be changed even after you deleted.

The reasonable conclusion is that a) limited circumstances are not construed as overpowered and b) this is less about game mechanics and moreso about your experience with the set circumstances.
