I couldn't really send overlords into his base until his onslaught was finished. I didn't have gattling tanks to back them up so if I did, he would've seen them coming from miles away and owned them with nothing more than a few MD's, and then most likely proceeded to drop a few pallys in my base and finish me
Yeah, I know. I wrote that comment from a replay-watching perspective - easy for me to say when I can see his base was nearly empty. Either way, I would've gone with two gats instead of that nuke, especially since you left it alone.
