Why is Darth vader required for 2 feats with certain other toons on the same day? There have been like 9 other battle days in this GAC where these feats could have been split apart.

Yes, one of them was available for 2 other battles, but there was no way of knowing vader would be needed for another in the last possible day of the whole GAC.

I can do them both at once, maybe. Depends completely on my final opponent's squads though.
