When Should I Buy Runes?

[quote=EzEon]Gonna add on to what everyone else is saying because it is the truth best time to buy runes is level 20 when you have access to tier 3 runes i suggest getting glyphs and seals magic resistance and armour first then depending on the type of laner you want to be ad or ap or support etc you can start buying marks and quents and when you gain enough experience in the game and understand what you can and can not do in general you can opt to buy the ap or ad or cd or whatever is cool glphys and seals but first rush your armour and mr they dont help much in early game damage but they very useful[/quote]
