PSA: Spoils of War
This little item here gives a passive called Spoils of War. It basically lets a support kill a minion that has about the same health, if not more, than the ones the adc last hits.
There are many moments when I understand not letting me proc this passive and hit the minion but when there are no enemies on lane, we're clearing minions under a tower, we're not pushing, or something like that please just let me get some cs/gold that shares to you too!
I'm pretty sick of having a full 2-4, depending on how upgraded your shield is, passives built up and no one on the team letting me use them when there is no reason not to.
