I hate that mechanic on Ezreal, if Ezreal Ult > Flash, then you cant really tell where the ult is going because if you look at his animation, It will animate in the direction he flashes, I fell pray to this recently and had to watch the vod because I swore I saw the Ezreal Ulting away from me
@@Fr0stedEzreal Kai sa W is different than Ezreal ult, you can cast W then flash and the W will shoot out from where you flashed to.. so you are buffering the ability and flashing right before it goes off. You can even cast Kai sa W during Kai sa R haha
Skill that need channeling allow for flash to be used but the skill will still come out from where it was cast and not where you landed, lux for example is another character that can do this.
