A new Mortal Kombat XL patch is on the way according to a Twitter post from NetherRealm creative director Ed Boon:
MKXL players! We WILL soon release a game-play balance patch & ideally would like to target its release along with the PC launch of MKXL !!
— Ed Boon (@noobde) September 9, 2016
Combined with an earlier Destructoid report revealing the likely date for the PC version (or at least the PC version of the Kombat Pack 2) to be October 4th, one can assume that the patch to update the aforementioned issues, along with the release of the full PC version, is currently targeting that first week of October.
