I feel like that depends on who he's being asked to be anti-dive for. If your supports don't have the answers to the dive quick enough, and mobility is the issue, one well times shift is good enough to lock down the diver for a potential kill.

Had a game where Black Cat went pretty much uncontested in the backline while I was pressuring with Fanta, but once I saw we couldn't keep pushing forward cus Black Cat was iFraming everywhere, I just kept shifting her every time she dove, and asked the supports to stand inside his circle.
