I liked the way BF 1942 solved this , using up a mag everytime you reload . <| sep |> TIL I ' m literally Hitler . <| sep |> I ' ll say it in the perspective from a top laner . Scaling HP seals give the overall highest amount of tanky stats lategame while flat armor seals will give you better tanky stats early . % Hp is terrible don ' t get it , flat HP is also terrible I ' ve heard it sometimes was used on adc ' s , supports but I don ' t think its good . IMO you can go scaling HP seals in alot of ad lanes BUT you need flat armor quints , armor quints are more efficient than seals . 3 Armor quints gives 13 armor compared to 9 from seals and thus if you want the great scaling from scaling HP seals then its a really good option and I do it often on tank top laners that don ' t need offensive quints . Put simply flat armor if you expect to take alot of physical damage in the early game e . g you are a champion like Riven who goes aggressive into the enemies minion line and trades heavily . Scaling HP if you are going to play more passively OR if you are in a lane where there is little physical damage . One other thing the way resists works is that the percentage dmg reduction from each additional armor you get , gets lower the more armor you have . This means when you are a top lane tank with 300 ~ armor in the lategame that 200 hp is going to do you alot more good than that 9 armor . Obviously HP also gives you less percentage bulk the more you get but its more linear than the scaling of armor .
