Damage checker

Riot needs to make a damage checker so that we know we aren't being cheesed by the game's calculations. Based on the fact that the damage checker screen is broken for about 3 years now, we need a reliable way to tell if there is something unfair in the game itself since the original "checker" the damage screen is completely unhelpful. Plus, Riot representatives say that they have no upcoming plans to fix the damage screen, so I say they should make a damage validation tool instead.
