Adding an item that causes onhits to proc every other auto?
Then check the ad junglers with powerful/unlimited on-hits. Aatrox, Vi, Shyvanna, yi, and Udyr just off the top of my head. This is an obscene oversight on Riots part. I played Xin jungle today and felt pretty powerful, but i was still scared of the enemy cass. So at least this new item didn't break him as hard. But I still saw my damage jump when I purchased devourer rather than after farming it up, which is a fail. As for others mentioned, I spectated some games today that blew my mind. the damage was over the top and god help the enemy team if you took scuttle/a dragon. I propose you simply remove the on-hit phantom proc and replace it with a bonus ad scaling. Then make it sated off 20 or 25 stacks. This, the ad junglers still need an extra item to take off with damage and they still feel like their jungler item benefits them.
that is bought by almost anybody who is AD anyway, well there was the Feral Flare but it's already gone.
