Marks - Armor Penetration
Seals - Dodge (I also feel HP/lvl works well)
Glyphs - Mana regen/lvl
Quints - Flat HP (used to run movement quints, but the flat HP ones are more beneficial IMO)
Armor Pen and Crit Damage. Quints as gold per 5 imo.
marks=seals=glyphs=quints= crit damage.
I always rock:
red = ar. pen
yellow = crit damage
blue = mana regen /lvl
Purple = ar. pen
