Getting hyped for newcomers is one thing. The other one is, well, what functions best competitively?
I mean like don't you just love playing with your (newcomer) character and doing the best you can with them, regardless of what limitations they may have?
The only stupid **** Brawl had were the Ice Climbers chain grabbing you to KO, MK being broken, and tripping. Other than that it was a good game regardless.
If Brawl had balance patches we'd be seeing a very different game, but it didn't, and most people seem to prefer Smash 4 now.
e: I should add, I have nothing against Brawl. It was a pretty good game but it is what it is.
