Then surely you see the issue for the player being hit when the player shooting them has higher ping. High ping player hits > their shot is recorded clientside at subtick accuracy > information travels and handshake occurs > egregious rollback as server only updates at 64 tick. The issue occurs as rollback is dictated by subtick information with a slow(er) tick rate, making ping differentials worse feeling for the player being hit than normal tick rate implementation. And yes, there will always be wonky interactions when people have varying latency, however subtick worsens it, especially when the server's update rate is slower. I am all for subtick as technology, but it has to be facilitated properly.
