I really don't know about this. I think what bothers me the most is that we are barely into brawl and this is being considered. We haven't even untapped characters full potential, or perhaps even all the abilities in brawl yet. I wouldn't say we're anywhere near with only like 7 months into the game. Focus on doing what we can with brawl before this is taken on. More than anything, this sounds like something fun to do on the side. I know its not trying to make melee 2.0... But these changes are too drastic and complex IMO. At least when you add Melee like features, which I am against as well, you are affecting every character in the game. But changing properties of individual moves and abilities of every single character? It would take forever to balance this appropriately, and mind you, we still have a baby metagame in brawl. How do you determine which individual hacks are better? What if some people want to tweak this attack one way, and others want to tweak it another? What are your guidelines? You have to determine properties of attacks, and how they will affect the entire 35+ roster of brawl, in different situations and conditions. I know this is all only a consideration and a possibility, but I think its one that will see little/no fruit.
If you could balance it to a starcraft level, then great. But I still think that its nevertheless a problem distributing it to everyone, and it could really segregate communities. The counter strike mod was easily distributed, and furthermore the creators approved of it. Hacks were encouraged. The makers of half-life actually started OFFICIALLY distrubuting counter strike. Do you think Nintendo would ever do that? What about the MLG? Seeing as it looks brawl will become part of the MLG titles... I don't know how that would work out, hacking brawl. That last one isn't a rhetorical question actually, I'm just curious.
