In theory yes,we hate to wait to see it in practice,you could have also said that for duskblade,no point in delaying the crit build,but i remember when Duskblade was buffed you didn't need crit and you dealt hell of a lot more damage than a crit build would do at 1 or 2 items.
I wish i filmed it,i managed to kill Nami with a single auto with lethality+crit Lucian,full hp,i remember Jhin doing 80% of the HP with one auto,so yeah,we will just have to see how it plays out,most people forget that it gives 25% AS and 8% ms when you crit,so it will be either a good first item or a good third item instead of a 2nd zeal,i know i wont go 2 zeals since you will have 60% crit with the new
and one
and 1 guaranteed crit with Stormrazor so it will feel more like you have 70% or 80% crit in short fights where you exchange only few autos,not to mention that it also gives AD AS and then on top of that more free AS and MS when you start critting which lasts for 1.5 seconds,more than enough to get 2 autos in and constantly refresh this passive,so you're trading 65 AD 50AS 8MS and a 100% first crit and a burst from Shiv for another zeal item that frankly wont be as worth since some %crit will be wasted going over the limit and you would have only +80 AD from IE that no longer crits for 250% to make up for the fact that you have very low AD
