A game that is so unhealthily centered on esports will inevitably be balanced by bandaids and become an incoherent mess that no sane person could ever understand. Remember how in 2011 we were all so happy that SC2 tournaments had mass appeal because you can more or less understand what is happening even if you've never played the game? Good luck with that now LOL. Mommy, why does that thor shoot 8 rockets but only do damage to one of the enemy air units? Son, thats because the anti-air capabilities of terran were deemed to not work well and were shuffled around in may 2016.
Anyway, here are my balance change suggestions. Increase supply to 500, make 3vs3 the mandatory mode of competition and create some giant-ass 3vs3 maps. We'd get a good laugh out of it at least.
