Playing Jin feels absolutely hopeless in ranked and I don't know what to do, requesting help.

Failed my Tekken God promos three times, it just feels absolutely impossible to consistently win against so many of the characters in this game with Jin. Outside of my frame traps it feels like I have absolutely nothing to work with without just having that ultra instinct and being able to predict what my opponent is gonna do and counter it perfectly. I'm just getting robbed by people spamming power crush on defense, parries on mix up, unblockables on offense, super oppressive stance mixups on block, high crushing counterhit launching strings, it feels like too much to be able to deal with with the kit I have outside of playing with inhuman precision by parrying all of it.

Are there any high level players that do coaching or vod reviews here? I've joined a bunch of discords for the game but no one ever wants to help or even play practice sets. I play in EU region on PC.
