NetherRealm Studios seem to be neglecting the PC version of their game once again since Mortal Kombat 11 has not received the day one patch on this platform at the time of writing. It was supposed to bring a pile of balance changes.
Mortal Kombat 11 day one patch brought a pile of balancing changes to the console versions of the game but the PC community didn't receive it, and it was four days since release at the time of writing.
This caused the PC players to have a wildly different experience since there were many balance changes that were supposed to happen.
As the video above explains, Shao Kahn is supposed to have another juggle combo that is not extremely hard to pull off but it would likely take Sonic Fox or another pro to pull it off properly on PC. The warlord's shoulder bash is supposed to pop enemies into the air a bit higher so he can continue to the basic combo for that decent 289 damage.
The shoulder bash works properly on PlayStation 4 and Xbox One and players are enjoying hammering people into the ground already but the PC players simply cannot do this combo, possibly rendering Shao Kahn ineffective.
Another two important differences from the Mortal Kombat 11 build that PC players got and the one the console players have is that Scorpion is fairly underpowered on the former and that Sub Zero is a bit too strong. Namely, Scorpion's basic combo is dealing 337 damage on consoles and only 295 on PC.
Needless to say, the early players didn't get the impression Scorpion was weak for no reason - NetherRealm were made aware of it and boosted his damage a bit but PC players still don't have that build of Mortal Kombat 11.
Likewise, Sub Zero's basic combo was deemed slightly too powerful so it has been tweaked to do 404 damage on consoles, as opposed to 415 on PC. These three instances are the only ones highlighted, but there are many more balance changes that were supposed to arrive on PC but didn't.
NetherRealm pulled something similar in the past, when they even temporarily discontinued support for the PC version of Mortal Kombat X.
