Talk:Armor penetration/@comment-180.191.29.249-20130108034139

Hi. I'm normally very into statistics and math, but my question is very much "big picture" right now. I'd like to qualify the statement "This cannot affect enemy armor beyond 0 to deal bonus damage." So, as a simplistic example, if I have 10 armor penetration and I hit an enemy with 5 armor, I would deal him my full attack damage, BUT I will not deal him the 5 "remainder" from my armor penetration stat? If yes, then it'll just go to waste, correct? I ask because I just started trying out LoL, and I was told by a kind veteran player that anything "left over" from my armor penetration will simply be counted as additional damage. But if this is not the case, then armor penetration, and magic penetration for that matter, is not as "universally useful" as attack or magic damage. Is this correct? Thanks in advance. --  CaL
