Berserker's Greaves should get the old Furor enchantment added as baseline.

Berserker's Greaves are by far the most commonly purchased boots for ADCs, a role that is currently in a very strange position in the meta. As it currently stands, the most successful ADCs are those who rely on Lethality and a long-range caster style of gameplay (Jhin, Varus, MF) as opposed to the more traditional crit-based ADCs. While I do think that the former should be a viable option, the strength of Lethality as well as the mobility power-creep in many brusiers has all but made traditional ADCs irrelevant in comparison.

In addition to much-needed adjustments to Lethality, I think the following would be very helpful:

Add the old Furor enchantment (12% more MS when you deal damage to a target) or some variation of it as a baseline passive to Berserker's Greaves. This will help traditional ADCs by giving them some individual counterplay to champions that can simply dive and destroy them. I don't think this would be over-bearing considering the current state of ADC in general, and also most other boots have multiple passives built into them, yet cost the same price as Berserker's
