idk, sometimes it takes playing another game to level up in the game youre currently playing. sometimes it is good to take a break if youve hit a wall, and a new game can give a fresh perspective
Different games have different fundamentals. You want to get really good at SFII? Play against any CE Dictator. If you mess up once in neutral you’re dead. You can’t rely on gimmicks or random stuff to win.
I feel i should respond to show I am still reading. Haha. The majority of this is helpful. But still the point wasn’t how to get better in general. But more a long the lines of finding a game that relies heavily on fundamentals. Because I do get lazy if the game lets me. That’s my flaw as a player. But I enjoy games that are more technical compared to SF5 and MKX.
Claw works pretty well for that as well.
You can act lazy in a fighter and lose most time that is normal and a given but you cant be lazy in MKX you would just be obliterated that is not a game that you can slow the pace of if that does not getting you acting I would not even bother with any games that aint hyper fighting at full crank or UMK3. You can be lazy to learn fundementals but not to actually do them that makes no sense that amounts to not playing the game what so ever
I feel incline to suggest Under night in birth.
i suggest vsav. good luck being lazy in that game 
edit- it is also a heavy fundamentals game from what i understand.
Hyper Fighting is the answer.
Super Hyoubal Fighter 2 <3
Don’t pick up a game to learn fundamentals.
Just play a good game like Guilty Gear
MvC2, defense or offense you need it all!
Koihime Enbu might be one of the games with the least dependance on blockstring pressure, pressure resets, blockstring mix-ups, and frametraps. There are mix-ups (for example, universal overhead/universal low oki) and frametraps (for example, stuffing the opponent trying to poke you to stop your throw), but outside of Hougeki attacks (a.k.a. Fatal Counter attacks), they don’t lead to big damage.
There are other games which have mechanics to severely punish pressure autopiloting, such as NitroPlus Blasterz (with its Vanishing Guard) and the Arcana Heart series (with its backward/forward guard cancels), in case you want games with airdash movement/chainable normals/jump cancels/roman cancel-like mechanics; there is also Immaterial and Missing Power, which (except for few characters) emphasizes screen control with projectiles (but unlike most other FGs, you can move through them towards a better place, but your opponent can hit you while you’re doing so; the game has an RPS of melee > grazing > bullet > melee) along with good movement decisions to get into your opponent.
Capcom vs snk 2.
This game will teach you how to space your normals, whiff punish normals and as a bonus, teach you how to deal with abusable “OP” (for a lack of better term) specials.
Thanks guys. I will randomly pick a few and go through. I am enjoy the Guilty Gear games. The seem to be what I was looking for. Slacking off often ends in a loss. And I really feel it isn’t a game for autopilot play and combos. But another thing I came to realize is the level of people I was playing against was a lot lower than mine. Which I think got me slacking off a bit. And since I was doing that I was losing games here and there and felt that it was just my level. A couple weeks back the guys I play with wanted to do some money matches, so I naturally tried harder to win and didn’t loose a single round in 20 or so games. Of course they no longer want to play with me because I take it to seriously. And I have had to find new people to game with. They guys and two girls I jam with now meet every weekend, and I can’t beat any of them. Haha. But it is the most fun I have had with fighting games since my teenage arcade days. But I am more aware of what I am doing now when I play and my footsie/fundamental game has picked up drastically.
