Out of all the good Tekken players/streamers the only one I know of that plays VF5FS is crazyDongpal but for the past like 15 streams he's only been playing Tekken 7 and some Yakuza 0 and I don't think that he grinds the game offstream. There might be others who do play VF but idk. I've seen Jae stream some SFV and UNICLR but not VF5 yet but I wouldn't be surprised if he did play VF5 at some point in time.
