But you're asking for a 1 bar solution to characters who's main form of offense is chip damage. Liu Kang has literally been changed for like 3 days, Cage just got nerfed, Shinnok and kitana I'm not super familiar with considering they both just got buffed. Not to mention 1 bar breakers will hurt other characters that don't actually deal as much chip, don't have 50/50 combo starters and have to rely on frame traps and grabs to open people up.If you combine this with an easier tech window some of these characters will be totally fucked.
IMO you should be punished for ending somebody's combo. There's no reason people shouldn't have to deal with the current cooldown other than making it easier for them. You got opened up and prevented the other player from dealing their damage, that's huge. Just because you don't have stamina doesn't mean you have no mobility and cannot stop somebody from just running in your face. Try to just run up on somebody good after they broke your combo and it can turn out really bad, even if it's not max damage due to run cancel.
Also if its one bar of stamina for breakers you'll be able to break a lot quicker after preforming risky, high reward tactics like running in 50/50 and etc. That's an offensive buff in a game that people complain about having not enough defensive options. Also characters with FBC pressure will be buffed because they can break a lot faster after putting themselves at + frames. Currently they can't break for a good period of time after using some stamina which is a GOOD thing and helps defense, especially in a game where normal attacks do chip damage.
