[Q]

My point is just that the restriction of repair would create more problems than its benefit is worth. That is of course just my humble opinion. If we want to prevent a fleet from going indefinitely from one combat to the other why not play without quantum reactor and solar panels? No matter how much supply ships you have in your fleet sooner or later you will run out of supplies and you need either to return or conquer an intact colony and build a resupply depot.
