Tbh if the brawl community wants the melee community to start liking them or whatever then they should host nationals that are brawl+melee. Genesis, Pound, etc....melee guys have run big Brawl events. Unless you count Alex Strife as a Brawl guy (and I don't, I think hes more of a smash TO in general; Zenith was his first event iirc and thats Melee), I can't think of a national that Brawl ppl made multigame.
Iunno, the major resentment is pretty simple. Very easy to solve. You don't even have to address the fact that most of us think Brawl is garbage (just being honest); plenty of communities have run with players thinking like that. Trust me, plenty of people hate AE or MVC3 or MK but they still attend EVO to play their favorite game. The resentment from the Melee side is that the Brawl community has taken everything they know from the Melee community, and has done almost nothing in return. In fact, its been the exact opposite. Melee players get treated like second class citizens on the site they built. You have to scroll all the way down to get to Melee discussion. All-is-Brawl doesn't include the Melee community at all. Fact is, most Brawl players wouldn't mind Melee being phased out completely. If it wasn't for the fact that our youtube videos actually get views, we wouldn't have any new players.
Melee players have done their part to help the Brawl community. **** they built it. And then they continued to run tournaments for it, even when they didn't like the game. If you actually want a unified community then the Brawl TOs have to step up and host a legit, grand-scale Melee tournament that rivals a Genesis or a Pound. Or else Melee kids will continue to view the Brawl community as parasitic.
I know no one wants Brawl v. Melee but real talk is real talk. Those are the actual reasons why there is a divide, and the only way to fix it is to talk it out. Its a little naive to say everyone should just let bygones be bygones and continue with the status quo, because the status quo is unfair. There is a lot of goodwill that has been lost and without actions to rectify that, the tension will continue.
