I am still firmly saying that the only way people should be going invisible is ending combos and off of d4, d4 invis can put you negative if it's crouch blocked, but the pushback is so good that f2 can still beat out a lot of shit. I have been using d4 invis f2 ex fb as a pressure tool and hit confirming combos off of it, I think it's really good, but I haven't gotten much feedback on this tbh.
