Steraks Gage nerf makes no sense. This is why
Sterak's Gage will be getting nerfed by 100 HP in PBE, but it won't make it less buyable. If Riot will keep nerfing Sterak's, becouse ADC's are buying it, after they finish no one will be buying this item at all.
The thing that ADC's and Assasins are buying this item, even if it was suited for Juggernauts, it's becouse of the meta. Team fights are much shoter, becouse of Season 6 changes to both ADC's and Assasins itemisation and changes to ADC's base stats, who can burst opponents much faster - Sterak's Gage grants both offensive stats and defensive ones.
I don't agree with this nerf. If you want to make Mordekaiser who has one of the best uses of Sterak's even more waker, you're making a step to the right direction.
In my opinion, if Riot want this great item not to be used with ADC's and Assasins Sterak's Gage need changes. I would be very dissapointed if they would nerf it even more.
