A Possible Solution to Lethality

So the original problem with armor pen was that was either oppressive or useless depending on how well the user is doing. Riots solution was to make an armor pen stat that scaled to the target's level which in theory would give some levity to the poor guy getting crushed and while allowing armor pen some scaling. HOWEVER, in reality all it really did was give more armor pen by the time they even finished the first item for everything except .

So my solution is this: Change the scaling on it to either increase or decrease the lethality based on the difference in level. For example;

if you had 60 lethality and both you and the target were the same level you would have 60 effective armor penetration.

if you had 60 lethality and you were 3 levels above your target you would have a ~33% decrease in effective armor penetration making it 40 and vise-versa. (note: this number is just an example and it would be up to Riot to figure out the precise numbers)
