Preset Runes

Why is it there's no preset runes for normal Supports? You claim that you need supports, but don't even let people learn to play them before they buy rune pages? There's Inspiration: The Timeless for jungle tanks (?), Sorcerer: The Calamity for mid, Precision: The Perfect for adcs, Domination: The Executioner for assassins, and Resolve: The Colossus for top lane tanks. Why nothing for enchanters - the majority of supps?
