"Balance" means little if the game does not prove fundamentally FUN TO PLAY, and into the medium-to-long term. No one will be watching SonicFox's 50-50 spam orgies if they've become bored of the game and moved on. Frankly, if it wasn't for Jakal's Kahn, I'd not even have watched any scene matches past that atrocious U.K. launch tournament... which nigh on gave me P.T.S.D.!
At this point, I'd encourage NRS to drop some tantalising DLC news -- to rekindle positive interest -- and make their intentions clearer, with respect to allowing customisation in tournament play and, however unlikely, loosening up the 3-slot limit for causal modes. They need to throw some meat to players, because with the vast majority of the player base being capricious casuals, those who want to stick with the game, need some reason to (beyond just the 'joy' of critiquing it, that is).
The way I see it, if people are already onto the "[insert character / set-up] is broken" stage of this game's discussion cycle, MK11 is headed for similarly short life span to the other NRS games that preceded it...
