Massive Fiora vs Vi bug
When Vi ults Fiora. Fiora can ult to force Vi to be stuck in her ult until the ult ends and doesnt tend to dunk her after.
In my honest opinion. From a counterplay perspective, Fiora should be pulled out of her ult so Vi isn't just left standing there half way through the dunk confused as fuck until the game fixes itself and throws her ult on CD.
I'd have to imagine it would also work on Maokai and others as well.
Imagine if Yi had this mechanic too? You know how broken he would be? If he could just dodge ults the are guaranteed to hit?
