What runes do i buy for my first 2 pages?

One AD and one AP rune page gives you the greatest coverage.

AP: Magic Penetration Reds, Flat Armor Yellows, Flat MR Blues, AP Quints AD: Flat AD Reds, Flat Armor Yellows, Flat MR Blues, Attack Speed Quints

Yes those runes are not going to be perfect but it will give you access to play every role without being at a disadvantage right at the start.

I only have one page that's all attack speed, but I mainly play Ad

I second Kaioko's recommendation.

i would buy;

3x AP Quints 2xAD Quints 1x AD Attack Speed Quint 9x AD Marks 9x AP Marks 9x Magic Res 9x Armour (yellow, glyphs i think?)

that will give you a nice mix for most, mid,top and jungles, while none of that is specialised you will have the ''core'' runes and can expand as and when you can. the reason for 1 AS quint is it does help on some champs, like Kindred for example but its good on all just not ''optimal'' for all.

the marks/glyphs are all pretty standard.

if you have any left over i would buy some tank quints and HP marks and stuff but thats if you play tanks, the AP will suffice for your ranged support (karma, zyra, bard, morgana, etc etc) and AD works on Thresh and leo, not optimal but it works well enough if your competent.

Flat ad marks Flat armor seals MR per level glyphs AS quints

Mpen marks Hp per level seals Flat MR glyphs Flat AP quints

There is your 2 most basic ad/ap sets

But that's if you want the most general useful stats on everyone when you have no specific role/champs you play. If, say, you're a jungle main and you mostly play Diana and Cho'gath...that's probably not your best 2 pages.

Mid ap main you may want: Mpen marks flat armor seals mr per level glyphs flat ap quints

then reuse half of that for a 2nd page like: Mpen marks hp per level seals flat mr glyphs flat ap quints

Idea is a page for vs ad and a page for vs ap, which def stat do you need pre-level 10. Armor or MR? Flip the glyphs and seals for either per level of the one you don't need for your lane opponent.
