1 armor is 1% more health against ad and 1 mr is 1% more health against ap... its just that simple. now you have to decide whether 1% more current health is more than flat hp+current percentage of ar/mr. thats all. Sadly you have to decide between ar and mr and thats the reason why flat hp is most of all the strongest way if you do the math. But Riot is not that stupid ignoring that fact and therefore there are some nice things like, vayne, madreds, malzahar, deathfire grasp and so on. If youre stacking lifesteal, high ar/mr is way more effective than flat hp: because heal is (true) heal, you're multiplicating your lifesteal hp with your armor to effective hp. 100 lifesteal-hp is 300 effective hp with 200 armor but without armor it remains at 100 lifesteal hp.... the higher your armor the higher your percentage heal. Because it would be op without counter there is heal reduction and true dmg. like ignite. what I want to say: What path you choose, there is a counter^^ mix it and you are on the safest way :)
