There are certain per-level runes which can be useful according to your needs. I like to use the per-level CDR runes on some champions who I want larger amounts of CDR on, but cannot afford to itemize for. MR per level and Armor per level can be used with similiar reasoning.

Per level runes start to surpass the others by ~10-13. They are more useful, perhaps, if you tend to play more defensively early game in favour of more guaranteed toughness mid to late game. But, on a whole, they are becoming less useful as games lengths are becoming shorter.

Mana regen and health regen per level are more or less useless no matter how you look at it.
