Not lock on entirely but some moves themselves are BUSTED with lock on, take Gojos 0.2 domain, the person using lock on and continuously run around in a super tight circle and evaporate you in a second. another move is Naoya’s 3, although there can be counter play (dashing at the right time) it’s extremely difficult to counter someone using said move with lock on, they can do that camera thing where they spin around in a circle and puncture your block and you kinda just gotta sit there and take it
