That's pretty true that Brawl has a less serious feel to it. And that statement isn't in any way meant to be an excuse for Brawl. The change was pretty darn intentional by Sakurai and his team. The fact doesn't change though that Smash as a whole is more likely to be forgotten by potential new players if no sort of smash scene has room to grow.
*Edit: Melee was a part of MLG for a few years until Brawl was close to release and MLG decided to drop Smash for more shooters. Luckily that year was the same year that Evo picked up Melee. The Melee tournament turned out really well. The Evo staff loved the Smash community and admired the number of attendees.
...then Brawl came out.
I don't know what really sparked Evo to be so certain of their rule sets, but they decided that items randomly spawning were good for competitive play. They claimed that it didn't drastically affect the outcome of the battle, which could be arguable if they didn't leave items such as the Smash Ball on. They said that having the smash ball was entertaining and the randomness was just as acceptable as parrying in Street Fighter. (which by the way is not produced by any sort of number generator. It's just that players happen to accidentally parry, but it's still in the control of the player) Finally, they said that they were against changes the rules from default. Well, the problem is default is 4 player ffa, all stages allowed with items.
The Smash Back Room tried to negotiate with Evo about having items and then when that failed, about what items should be on, but the organizers hardly listened at all. The Staff there claimed that they would hear anyone's case if it was well supported, but they seemed to notice their own members' opinions much more than the opinions of those who were actually going to play the game.
From what I can tell, there wasn't as big of a turn out of players as there was for Melee. At the very least, the number of pros was very low.
