I only knew about it because that patch dropped when I started playing the game, I never did PvP myself though. You can look back at comments/threads to see how people hated the ring. The point is lock-on makes fighting easier (and changes controls as well) and Souls combat doesn't work very well without it. Why do people even lock-on if not locking on is just as good or better? I don't have any trouble targeting enemies / fighting in groups in games with better combat like aforementioned Dragon's Dogma or Bayo nor do I have any issue targeting specific enemies in the Batman games (doing the one-hitkilltakedown moves against the more dangerous ones for example) when there's like 20 of them at a time.
In games like Batman and Bayonetta you’re bouncing and jumping all over the place so it doesn’t make sense to lock onto anyone. Idk why you always compare Souls to games like these anyways. I don’t even know what I’d consider to have inspired Souls combat in the first place, as that’s one of the reasons it caught on so much is being different at the time. When I google “games with Soulslike combat” all that shows up is a bunch of games that came after it.
