I hate runepages, though. Expensive to buy, expensive to fill.
But so helpful. 25 Armon penetration & 6.5 mana per 5 on one page - this means true damage as AD champs early on when people have less than 30 armor, and I won't run OOM. +38% attack speed on one page, extremely useful for guys like Teemo or Kog'Maw. Runes to make jungling so much faster, to give late game power, lane presence and so on... Runes are really helpful, and once you've bought the few champs you like to play, invest in runes. Maybe get tier 1 runes since they're super cheap, and when lvl 30 get the tier 3 runes, ignore tier 2. I got 11 runepages, all of them full, and I still feel like I need more.
Also, this happened.

Fizz lost connection mid-game, but we were losing hard all the time. Hecarim though he was a Tryndamere with permanent Endless Rage, Ahri considered herself to be a melee support (always hugging nasus) and blitzcrank wanted to show off his megahooks by pulling Nautlius or Nasus into 200 hp Caitlyn. Cait did okay late game, but mid-game she just kep wasting ultimates on a Nautilus who although had only 300 hp, he also had 1000 hp shield.
