Spear of Shojin suggestion
In order to stop Yasuo and Zed and other AD melees that shouldn’t be building this item what if the item included a health threshold in order for it to work?
Bruisers build a mix of health and AD, unlike other AD champions that looks to build straight AD to maximize on their damage. Even most lethality builds are just long swords. Health is the one stat that separates bruisers from other ADs.
Similar to warmogs, this will make sure the item doesn’t grant insane damage reduction if you build it early and will be more geared towards a third item or so for when real fights start to occur more often.
Not sure what health threshold should be but the idea doesn’t sound too far fetched imo.
+ Spear X Atma can be build on every single Champion in the entire game incuding ADCs, Mages and Tanks and you'd still do well with. xD
