I am not really sure if I want balance patches in my SSB.
From time to time, the only way that devs find around balance issues in games is complete redesign of some aspect of the gameplay. Let's look at Project M. I didn't play it, because I'm not importing/pirating NTSC game when the final version is supposed to get ported to PAL Brawl (and I think that the PM team could find a way around incomptaibility issues, but whatever). However, looking at the mod notes, I was sometimes quite disappointed. Nikita thrown out of Snake? Koopa Klaw replacing Flying Slam? Din's Fire getting a complete mechanical redesign? (I remember side Bs the most, but there are more of these.) I have played these characters because I liked these moves in the first place... Project M is kinda innocent, though, since you can unlaunch it.
Meanwhile, there's the thing known as Divekick. I'm not sure if it's a fighting game, but I sure like to play it with friends from time to time. Guess what, a patch for Divekick was recently announced. It won't be removable, it will replace the original on download servers, and it won't have an old mode switch. And it does more than changing numbers and adding functionality updates. For example, there is one character which had an absurdally gimmicky normal attack and slightly more normal gauge-powered air attack. The patch, among other things, switches it around, leaving us with what even developers consider "an almost new character". And the old game will be gone. Unless you crack the old version, or keep your device offline, or something. But these are workarounds.
I have no problem missing an infinite combo from old version or Falcon Punch doing 20% of damage instead of 33%, but if pre-advertised features of characters get removed and replaced by balance patches, screw this.
