They really need to give a third free runepage now that new champion select + autofill is the norm.
With autofill rearing its ugly head, now you need to be ready to be dropped into any position at a moment's notice, and we still only get two free rune pages to work with.
Yeah, sure, the standard AD page and AP page approach works in most cases, but what about jungling? Junglers seem to generally want attack speed runes (usually reds), with only a couple exceptions, and a page tailored for the jungle isn't of much use anywhere else for the majority of champions.
This wasn't really a problem before autofill, but now...
does fine with AD marks, as quints, armor seals and MR glyphs.
so does Ashe.
Problem solved. Enjoy!
