I play Brawl+ for Combos. To be technical, combos that, if performed correctly, are guaranteed. You know... Those things that are almost non-existent in vBrawl. Those things that are the foundation of every good fighting game in existence. I knew with the reduced hit-stun combos would be harder to perform. The hit stun is far to low for me to do anything major. I had trouble with Falcon's Nair -> Nair. I shouldn't have trouble with something as simple as that, yet I do. I can only hope it's because of the changes it got. I can manage to combo into the Knee from a Nair/Uair if the opponent is at lowish-high damage, but the should have been dead by then. Jiggs also weeps.
I know that the makes were aiming at making the game deeper by making prediction and reading your opponent bigger parts of the game, but killing most of the old combos isn't worth it. The day that Falcon's Dthrow -> isn't guaranteed is the day Smash dies for me.
The only things liked was various nerfs and buffs. All of Meta's Changes, all of Sheiks changes, Link's Up-B nerf, and Snake's changes are a few examples, but there are more. But that isn't even close to being enough to justify playing it since it isn't fun.
