You know what one of the biggest issues with ADC is right now? Itemization.
Their Itemization is really really easy to get to. Almost all of their items have simple buildpaths with mid level upgrades that have good passives.


Of the Above I think Zheal may be the worst offender. The price, combination of AS and Crit, please movement speed, AND the fact that it has 3 different upgrades if something happens after you buy it, is a little ridiculous.
Before blanket nerfing the class (which may or may not be needed). I'd honestly just like to see either
A-Other classes itemization becoming just as smooth (Giants belt builds from 2 ruby crystals, NLR upgrades from Blasting Rod or 2-3 amp tomes)
B-Intentionally making some of the build paths less smooth, akin to Runaans last major nerf.
C-If the mid game pieces are in a 'good place' - or would hurt the upgrades intended for other classes, increase combine costs to get the upgraded passives/new abilities.
