You have got to love the "pro patch" propaganda in the first post. While Injustice's balance changes were well-managed, with some exception. when the term "bad patching" comes to mind, most people in the NRS community think about Mortal Kombat 9 for the following obvious reasons.
Cyrax - in an attempt to address highly damaging reset combos, the result is extremely damaging reset combos and a safe buzz saw.
Ermac - telekinetic push recovery inexplicably increased by several frames due to the very early community perception that Ermac is an easy character to use and win with (i.e., "Easymac"). Ermac was ultimately never better than a mid tier character at any point in the game.
Kano - upball receives a major buff. Upball buffs are reverted two weeks later. Knife toss recovery is inexplicably increased by a couple frames. Freddy is released as a DLC a month later with better zoning than Kano ever had.
Noob - irrelevant buffs that lead ultimately to nothing. The character was too unsafe when the game was released. The character was too unsafe when the game died. Early in the game's life span, the Johnny Cage community tried to convince everybody how "broken" Noob's zoning was.
Sheeva - never received any significant buffs or changes despite everyone and their mothers knowing how horrendously bad the character was.
Skarlet - total frame data annihilation of dagger cancels as Kabal spams instant aerial gas blasts 250 MPH.
Smoke - in an attempt to address smoke bomb OTG, the result is extremely damaging reset combos. Smoke community fools and morons demand a "low that launches" to complement their overhead. Thankfully, NRS never listened.
Sub Zero - reset combos are removed. Cyrax and Smoke keep their reset combos, which ultimately end up twice as damaging as Sub Zero's. In addition, Sub Zero does not have a single mid attack that connects on low hitbox characters.
The lesson of the story is, patching is neutral. Patching can save the game, but it can also ruin it. Take your time and think about everything very carefully before you start buffing and normalizing.
