The old master returns.

KGB seems to consistently lose vs Circuit hovers even in mirror situations because Circuit's extreme aversion to staying in the engagement works well with Scalpel. This may also be the case on the smaller maps.

This is nothing new though. Hoverfac is an abomination where the only units without aoe are the designated assault and riot. Additionally, solving scalpel pretty much requires either a combat predictor/simulator that is a lot less crude than comparing threat colors; or switch to a hardcounter (for AI, likely in the form of a stronger bullshit skirm like Wolverine or Firewalker).
