the only thing I would consider doing for now is 7% IAS on wep + 7% IAS on one ring
both of these will give you considerable reduction in frames per attack (more attacks per second)
Generally you want to drop crit on helmet+1x ring since PE is always run in HOTA setups and it provides APS.
edit: Considering DPS optimization when it comes to APS and CC for Hota is very tricky because you have to consider a lot of variables when your trying to perfectly min-max your setup.
So that's why GENERALLY I suggest drop crit on helm + 1x ring and run APS as this will fit into most group setups optimally.
I've also noticed people dropping 10% crit on necks, keep in mind this information may change but atm I would say this is a really bad choice if your looking to perfectly min-max your setup.
10% crit for one primary is very strong roll.
They drop 6% cc on helm and 10% cc on neck because the supports run iceblink gem. Puts you at ~98% crit chance with 185 max fury, iceblink on support class, max cc on 2x rings, gloves, bracer, & paragon.
