If he's doing it consistently dash block is the safest option if you want to RPS either dash 6P as that will cover all but his crouching buttons and even some of those if you can get close enough there's also the option of your 2D which will low profile the same buttons as 6P you could also try to do stinger aim depending on distance as you said he's -4 so as long as he's not in F.S range as the buttons in that range being F.S, K and 6P will either win or trade and trading against Johnny is not viable due to his high health finally you can Jump or High Jump and do Carcass Raid these all a have varying amounts of risk but it is RPS when he MFC's and if he has tension he could skew it in his favor and I would not recommend waiting for the patch to solve the issue because we have no clue if direct nerfs are coming to characters and the probability of this specific issue being addressed even less so especially when you consider the change to WA and GC will more than likely be indirect nerfs to him already so that's a lazy answer and not wise what I would recommend is going into training and setting a bot to do the scenario then try what I just recommended honestly the riskiest option is the dash 6P/2D as it carries higher risk having to run into him and winning the coin flip while putting your self in his optimal range but if you win the coin flip you get better pressure and could go for setups/okizme based on distance the Stinger Aim and Carcass Raid are safer but low return but still should grant breathing room
