Since i haven't really posted what i expect from fighting games, the only company which i care about its NRS, so what i do expect from NRS in the future as an improvement is going to be what most ppl said already, so if your suggestion happens to be in here, it means i agree with you, be warned that i tend to make long posts, because i like to go into details about things, will try no to make this here:
1 - Net Code has been improving from game to game, if they can make something even better than I2 netcode, i'm always down.
2 - Get rid of region lock, this stuff sucks and divide communities, instead, people who plays online should be able to look battles by Region.
3 - Rage Quitters getting a quitality its a fun, so bring it back (more into rage quitting punishment down the line)
4 - A mass overhaul to the input system, as i said before in this thread, coding the game to know the difference between holding a direction and tapping it, code the special moves with a time window to execute, apply both when making specials, so a character with a command normal won't accidentally trigger a special move, coming out of a crouch block, or blocking with D-Pad pressing back because of habits while just trying to use a command normal.
5 - Training mode WILL NEED to have record/playback slots, that allows players to record multiples setups, 5 blocks are good, just don't forget to add a frequency ratio which one can set from 1 to 10/20 that indicates which one we want to be played often.
6 - Ranking system is needed, its time we get to level up from Humans to Elder Gods, have a leveling system to play ranked, just don't forget to put options in search mode to pick 1 to 3 levels above or Any level if one needs so matches won't disappear as the game life's cicle ages.
7 - Ban people from ranked for at least 48H if they rage quit, so they can take their salt somewhere else
8 - Hability to mute players online, some people are just annoying
9 - Don't get rid of the replay system, and give us backdashes that recovers fast, the MKX ones were hilariously terrible, too long and too slow on recovering.
10 - Last, DON'T FREAKING GIVE US HALF SCREEN NORMALS AND LIGHTSPEED RUNS anymore
And that's really all that matters.
Need help gimme a call.
