Tier 2 Runes should cost 80 IP a piece and be 99% effective as tier 3
The stipulation being that you can only have 18 tier 2 marks, seals, and glyphs. And only 6 tier 2 quints.
That way new players can have 2 full rune pages without blowing 25k IP, which takes way longer to get than it does to get level 30.
And then, as they continue, if the want additional rune pages for new champions they unlock, they can buy those. But for casual players and new ones, tier 3 runes and champs and rune pages cost WAYYYYYYY too much
