Runes

Still being south of 30 and working on completing my first rune page has forced me to be very judicious in my IP expenditures. In a way I feel like if I can't fill (for my level) a page specifically built for a given champ, I need to wait until I can before I can even try that champ.

Hence the constant maining of Garen.

The first page I'm looking to polish off is:

Mark of Desolation - 410 IP - Armor Pen +1.66

Glyph of Focus - 820 IP - CDR -0.65%

Seal of Evasion - 820 IP - Dodge Chance +0.75%

Quint of Desolation - 1025 IP - Armor Pen +3.33

After that I'd like to expand with:

Mark of Insight - 410 IP - Magic Pen +0.95

Glyph of Warding - 205 IP - Magic Resist +1.49

Seal of Clarity - 205 IP - Mana Regen/5/Level +0.1

Seal of Resilience - 205 IP - Armor +1.41

Quint of Potency - 1025 IP - AP +4.95

Quint of Fortitude - 2050 IP - Health +26

Focusing on the runes currently at my disposal, what champions besides Garen can I branch out to? Poppy?

What other runes should I be considering?
