Starting Tier 3 Runes?
I currently have a rune page with 9x Greater Mark of Attack Damage, 9x Greater Seal of Armor, 9x Greater Glyph of Magic Scaling Resist and 0 quints. I use this general rune page for everyone so far. I am planning to get more Tier 3 runes (mainly focusing on getting some Tier 3 quints) during the sale.
I don't have a lot of IP saved up, but I'm wondering what would be the best quints/runes to get? What would be the best quints/runes to start out with (for 1-2 general rune page(s) that would work decently on almost any champ)? I'm thinking that I should probably start by getting 3x Greater Quint of Attack Damage (Flat AD Quints), then if I have enough IP, get 3x Greater Quint of Ability Power (Flat AP Quints). Is that good? Is there any better quints to start off with?
TLDR: What would be some good T3 Runes/Quints to start out with? (general rune page(s) that should work on any champ)
