nice maths. At first glance i assumed it was surely a buff, but i ran them myself and come to the same conclusion. https://i.imgur.com/AWDZAeG.png
If you play soloQ and you don't plan to get to 4 items, don't take the new IE.
And get what? Remember galeforce is getting pretty hard nerfed. I agree now that this isnt really a marksman IE buff, but for champs that only decide between IE and galeforce (e.g. Jhin, Jinx, Aphelios), I think IE will now win out generally.
Also, Yone/Yasuo crit damage is hard coded I think, so I wonder if IE crit modifier will even affect them if they dont also go and change their numbers.
