Is the blast zone the distance from edge of stage to death?
If so, bigger is better IMO. That way you can actually die from not being able to recover. In Brawl it felt kind of rare to not be able to recover
I guess I was subconsciously comparing it to Melee. I still have to play with humans to decide whether it's a good thing or not. I'm not liking the ledge mechanics though, I still instinctively edgehog even it doesn't do anything now
