No carrier pigeons, but 'patch' and 'hotfix/tweakvars' are still talking about two different methods of delivering changes.
Also as stated before, why would you assume that the incremental changes are based on crying, and not that people mainly cry about the things that needed prompt attention in the first place? Generally if a developer thinks there's a big enough issue to warrant correction, there are tons of other people who have noticed it and are complaining about it as well.
So far they've made slight nerfs to Kung Jin, Raiden, Sub Zero, Quan Chi, D'Vorah + Erron Black, and given Kitana, Kenshi, Takeda, Kotal, Shinnok + Mileena some help. Looks very reasonable to me.
In relation to this game, i suppose your idea of a balance patch and items that should be hotfix are different than mine. we can agree to disagree.
Kung Jin dmg nerf? Scaling issue, should have been hotfixed
Raiden? Shocker scaling should have been hotfixed, frame data changes no
Sub Zero? Grandmaster hit with a cryohammer. Knee jerk reaction and heavy handed, unwarranted
Quan Chi? if bat cooldown wasnt applied properly, then yea hotfix. if it was and they just changed it because people cried, then no
Dvorah? scaling issue, hotfix it
Mileena hitbox issues? hotfix it
Jacqui hitbox issues? hotfix it
Kotal blood totem disappearing on hit? hotfix it
but the rest of it? nah. Lets take a look at shinnok. Hell sparks was overly buffed in my opinion and not thought out. I'm willing to bet another balance adjustment - I'm sorry, hotfix - will be made to to re-balance him, and that will just prove my point.
