Users with priority mode turned on, like priority mode.

Users without the power badge, don’t like priority mode and want more visibility to users with priority mode turned on.

Making power badge more permissive, increases spam. Makes everyone unhappy (except the spammers)

Solve for X.

Power badge has flaws, but haven't seen a concrete proposal for a deterministic alternative to the power badge.

Most suggestions for improvement are: "sounds like a hard problem, but whatever system you put in place should give me the power badge." :)
