Runes: armour pen / atk speed

[quote=Booshido]Just wondering what you're opinions on would attack speed marks and quints and then building a last whisper say, 3rd item, E.G. Boots/Manamune/Lastwhisper? I do the same with GP by getting crit chance, then last whisper a bit later. They faster you hit the faster they fall right? >.> Armour pen runes are probably the most important ones in the game, so just wondered what everyone thinks[/quote]

[quote=Considereth]Isn't attack speed a lot cheaper to buy in items than armor penetration?[/quote]

[quote=Booshido]you would only need a last whisper, i dont want to buy armour pen i want to buy AD items, not attack speed items[/quote]

[quote=Booshido]if i build manamune i wont need mana regen, and last whisper, won't need need...flat armour pen... for ezreal.. [icon=Berserker's Greaves] [icon=Manamune] [icon=Last Whisper] [icon=Infinity Edge] [icon=Phantom Dancer] Full attack speed page, 38% <3[/quote]

[quote=Searz]Duuuude.. A page with only AS is crap >.> I think I'll make a graph for AS marks vs ArP or CrC. Not that hard now that I have a standardized AS formula.[/quote]

[quote=Jebus McAzn]The issue at hand is AS runes and Last Whisper vs. ArP runes and some other source of flat penetration/reduction. I suppose AS runes are fine on anyone that needs it, but a lot of champions that rush I-Edge and LW aren't going to have that sustained damage output until well into late game.[/quote]

[quote=Booshido]yea flat armour pen ftw, last whisper sucks.[/quote]

[quote=DEWO]AS marks are viable in my opinion only on heavy junglers like Udyr/Trundle/Olaf. In any other situation ArP > Anything on Marks.[/quote]

[quote=Searz][quote=DEWO] AS marks are viable in my opinion only on heavy junglers like Udyr/Trundle/Olaf. In any other situation ArP > Anything on Marks.[/quote] Pretty much. There's a reason they are the only S-rank marks ;) Though a few hybrids have more use of AS than ArP.[/quote]

[quote=Restrictnine#5232]To be honest, its preference. I almost always go AS runes unless its someone like urgot that makes absolutely no use of AS. I go AS runes because I NEVER cap out on AS in items even if im using an AS build. it also makes early last hitting much easier, and arp is pointless if ur getting last whisper later anyways.[/quote]
