Nerf Nerfing and Buff Buffing
Instead of nerfing champions/items who seem a tad too strong I think Riot should buff natural counter champions/items into viability.
Barring some truly game breaking things like, and this is my personal opinion, %hp true damage. In such cases Riot should rework these champions/items/abilities into something more healthy whilst not losing too much of their identity yet providing better options to counter them.
