That’s not how killer instinct has ever worked, nor will it. The game started with the person breaking being at huge advantage, now we’ve reached a point where you return to neutral which is pretty fair for all. What you’re suggesting is way too far in the favor of the person being broke. Your reward for opening them up was the initial damage, if you are going to risk continuing the combo you do so at your own risk.
Also think about how much more annoying fighting gargos would be for you with that change. If he has two minions out and you break him, he can just setup a nasty mix-up or run away or put out a new minion while you are stuck there doing nothing unable to even jab out to get rid of his minions.
Side note: gargos’ greatest weakness is footsie range, not up in his face. So the way breakers work now is actually good for most characters against him
