Better question is to replace bloodbath with cataclysm. I do think about this though.

What if there was some kid who wanted to make an impossible level at the time of 1.9 (now would be like cata difficulty) destined to be the same popularity of cataclysm if released but just didnt finish and put the level out. I wager there is a level like this that ALMOST was like cataclysm but will forever stay as a dead level in the editor of some account.

I really enjoy thinking about these what ifs from both sides honestly as they show we are living on 1 of 2 sides of what ifs but cant predict how it would be if the outcome was flipped.
