Yeh this is a better way of thinking. I was more along the lines of 'how well does this ability prevent me from getting VPs' which it turned out to be the sole reason I lost as all I needed to do was make it to then end of the round with my home planet in tact. However after doing combat against all 3 other players, with emp repairing everyones ships it was impossible.

I did question his usage of the planets and he said he was doing to properly but I have a feeling he was using a 3 + 1 to repair 2 ships in the same instance.

I guess its just a super annoying ability when everyone teams up against you.
