I'm looking to try to go competitive and play support on a team. My runepage looks like this:

Marks: 9 magic pen (Possibly trade for hp per lvl)
Seals: 9 mana regen per lvl
Glyphs: 9 cd per lvl
Quints: 2 gold per 10, 1 mana regen per lvl (trade maybe for movespeed quint)


What are the best runes to use?

3 gold/10 quints with gold mastery < start the game with a gold per 5 item
mr/level glyphs
armor seals or armor seals
magic pen marks or more mr/level lols

Marks: 9 AD
Seals: 5 mana regen per 5, 4 flat armor
Glyphs 9 Flat AP
Quints 3 Flat AP
Masteries 20/3/7

Here's mine:

quints: gold
yellow: flat armor
blue: manaregen/lvl
red:flat mana regen or penetration (for sona)

Seems fine at 1700 elo

Masteries 0/9/21.

This is my current set up, Mastery's / Runes

I main Support (Sona, with S1 at a 60% win ratio over 100 games at 1450+ Elo)
