That's exactly why I'm asking! I played one in 3.5, and was liking it more conceptually than in execution, partially because it was a little underpowered. Since almost every class got a little juice in Pathfinder, it just seemed like using it straight up would be making that problem even worse. I'd really like to find a good fix.
Hmmm. if we remake the auras to be more about making life hard on your enemies, instead of boosting your friends we might be able to keep them around.
