I know that what I'm about to say may sound ridiculous & also impossible.. however, I'm putting this on the table still.

 Either a Street Fighter IV like tier system that ties more into each characters available moves & overall character specs--stats during online gameplay.

 Or, some sort of balance selection system (Casual and/or Expert) that works something like the above tier system, but without players and characters having to be constrained & limited by the above tier system overall; unless warranted by above said selection.

 The reason that I suggest the above premises is not only that I am frustrated with people complaining that the balance in certain video-games & characters alike are unbalance and take away from the casualness of the video-game, and it's playability overall..... I also would like to see those same concerns addressed in away that may not limit the potential of a development team and the video-games that they may decided on developing--producing within the future!

 Personally, I see what I suggest somewhat in the same way as having a difficulty selection option during single play within any video-game; however,applied in a multiplayer online fashion instead.

 Yes, I know that the above premises opens up a whole new can of worms, more-then-likely; however, maybe the actual smart Guys & Gals can & will be able to either solve or workaround those unseen technical concerns--issues; and once that is accomplished maybe all further online multiplayer video-games will suit the preferences of a larger majority of video-gamers & Developers alike (during & after development).

 Why mess with the normal ways of doing things, when Developers can just downsize there overall product by cutting or limiting certain aspects and elements within their video-games as they see fit ?

 Well as much as I don't want to answer My own question.. I will say that even I would sometimes prefer to be able to select either a Casual or Expert mode while playing any type of online video-game; given the right constraints & extra options that each selection may or may not provide depending on the selection maid. Plus, as i already stated (which may be wrong; in a sense), I also would like to see the concerns about online video-game balance addressed in away that may not limit the potential of a development team and the video-games that they may decided on developing--producing within the future.
