I think you have a valid point. This isnt the first Ive seen it, but it might be the first time its been posted. After roster gets so low, the arena dynamics are very different than they are during primetime. If not a disablement of the balancer at least a softening of it, because the 10 pilot difference in USPT is a minor % difference, but early AM it could equate to a huge ENY value.
Just as an example:
IF TotalRoster<175 then ENYDisable*.75
IF TotalRoster<150 then ENYDisable*.5
IF TotalRoster<100 then ENYDisable*.25
IF TotalRoster<75 then ENYDisable*0.0
