Honestly, I feel like the new runes/masteries system, is so tunneled, and so "not diverse" that I actually miss the old rune system. You could customize your pages into whatever you wanted/liked.
Full crit dmg trynd/gp? Check.
Full movespeed Vlad/Singed? Check.
Lifesteal Draven/Caitlyn/Adc? Check.
Spell vamp vlad/singed/etc..
I really miss the fact that before, even though some rune setups were "meta" and unchangeable, you were able to customize your runepages however you wanted, for the champ you were looking to play, and is it just me, or do some other people actualy miss this "mini-customization" options that have existed in the game? :/
