I think the likelihood of draws depends entirely on what sort of mod you put these conditions into. Obviously if you put a "fracture opponent" condition into a mod with very high fracture threshold, then you'll be in for many draws. I'm sure whoever sets up a public server will make an effort to make it balanced, if he should choose to change victory condition.

I don't even care if these ever make it to public rooms, as long as I can set them in my own server :P
