There is really only one problem with ADC itemization
Stattik Shiv + IE.
This is a very strong powerspike at 2 items, as Shiv's Crit value as well as energize value get amplified by the purchase of IE. This burst of damage makes ADCs that build the two items much stronger than they would be with another zeal item if they crit.
That being said, I'm seeing a lot of posts claiming crit itemization as wholly overpowered. But, if we take pre-marksman rework itemization and current itemization and compare them side by side, pre-rework wins in terms of DPS (Think PD having 50% AS and 35% crit), while having just about the same cost.
Which leads us to conclude: is the power of ADCs in the meta then a result of a couple of items (Shiv being the main culprit, and Shiv + RFC as 2 items), or is it because of something else. Or, more likely, it is some of both, but very likely the latter.
(2900) to
(2600); comparatively, shiv is extremely over loaded and cheaper.
Not to mention the fact that unlike other classes marksmen simply get handed all the stats they could ever want.
