Percent Health True Damage
True damage alone is an annoying mechanic in my opinion, but why the hell does Vayne and Fiora, more specifically Vayne, get this in their kit? You cannot stack health or itemize against it. There should be a maximum amount of true damage that a Vayne can do, or some kind of nerf.
requires double the hits from your opponent to proc on-hit effects.
are items you can build that work well against tanks. I don't think that a champion should be able to walk up to any champion in the game and delete them regardless of their itemization.
