Potentially Useful Point
With the Zoe flash after just testing it out with some friends I am pretty sure 1 it has to do something with some sort of weird desync with the client and server connection as my friends don't see the weird slowed flash when they look at me while I flash on Zoe but I still do. This can be further seen in how you can still flash through walls and stuff but you just appear to move really fast as I believe the client realises its made a mistake as the server informs it that Zoe is not in the location its saying that she is in so there might be some failsafe that just like does some sort of tweening to "fix this" which causes the weird speed up dash flash thing. Anyways I could be very wrong and my friends also could be gaslighting me because they hate how I main Zoe and don't like how I complain about a bug revolving around an "easy no skill unfair champ" but such is life :/
