People are sensitive, fragile, and insecure. The only reason anyone has come to defend Brawl over the years despite all of its shortcomings is because it's what they play and can identify themselves as members of a community who play it. They perpetuate arguments to defend it BECAUSE they play it when they can't bring themselves to go back to Melee when the reality is that game isn't very good at all competitively or casually compared to its predecessors.
Bottom line is that everyone looking forward to Brawl who lined up at their local game stores that fateful march day originally wanted a remake of Melee with added content. Sure, there were some people who didn't want a replicate with all aspects intact (some players disliked wavedashing, as an example), but the overall product that was not only expected, but hyped for, was Melee 2.0.
Anyone denying this is usually lying to cover their insecurity, or was a Brawl exclusive Smash player and was never fortunate enough to play Melee or Smash 64.
