My answer would be selfish because I'd like it patched now, for a few reasons.
1 - I don't find MK11 to be all that exciting to watch in its current state. Namely Sonya, Geras, Erron Black, Scorpion (basically, all the character considered high tier). I'd just like things shaken up a bit. Again, this is selfish because it's only June and the game has not even been out 2 months, so I know this would be foolish to do so soon.
2 - Kotal is not only shitty, but he's boring as fuck to play. He was my favorite character in MK11 and I just have no desire to waste my time with him currently. Shao Kahn feels like Sektor in MK4 Gold by comparison. Again.....this is selfish, I understand that.
3 - We only have 2 tournament variations per character, and a lot of them are shit that appears to just be thrown together. We should not be taking steps back in a sequel. Sure, there were plenty of variations in MKX that weren't viable, but at least you could see what purpose they were supposed to serve. Every character should have at least 3 tournament variations with a clear focus (i.e. zoning, counter-zoning, rushdown etc.)
4 - I hate how Fatal Blows work (added this after the fact). They need to be changed. They shouldn't regenerate. They should do less damage. I'm so sick of seeing them. Many of them completely ruin the focus of this game, which is supposed to be neutral.
Having said all that, I'm still having fun playing the game, but I don't feel like it has even come close to reaching its potential. I don't think a small balance patch to bring some of the lower tiers more toward the middle of the pack would be all that bad, but I know we are too close to EVO for that. I don't think we should be waiting a year to balance the game, though. If I have to watch Geras' F212 or 111 for the next year, I may throw myself in front of a bus.
