Almost every single person in this thread in favor of removing tier 1 & 2 runes seems to have missed the update to them where their prices were drastically reduced and most of the rarely used ones were removed. Even many people who think they're fine how they are right now don't actually realize how cheap they are. One person who thought they're fine said "A full tier 1 runepage costs like 1500 IP and tier 2 isn't much more expensive."
Buying 3x every quint and 9x every non quint of tier 1s right now costs 1035 IP. ALL OF THEM. Not one rune pages worth. ALL! Just 1035 IP. Quints are 15 IP and non quints are 5 IP at tier 1. That's dirt cheap. A single full rune page of tier 1s (at lvl 30 with all slots unlocked) costs a mere 180 IP.
Tier 2s are 100 IP per quint and 35 IP per non quint. AKA 7080 for 3x every quint and 9x every non quint tier 2. One full rune page (again, at lvl 30 with all slots unlocked) costs a mere 1245 IP. Note that that's less than one person in favor of not removing them thought an entire tier 1 page costs.
Compare these to tier 3s. A single tier 1 full rune page costs less than the cheapest single tier 3 runes (205 IP). A single tier 2 full rune page costs less than the most expensive single tier 3 rune (2050 IP).
Meanwhile just 9 tier 3 glyphs of flat CDR costs 7380 IP. Tier 3s are the problem. Tiers 1 & 2 are now fine.
P.S. Some fun math I decided to do: If you only buy tier 1s from lvl 1 to lvl 9 you'll have spent 90 IP on tier 1s (assuming 2 completely unique rune pages, never replacing runes once bought). From lvl 10 to lvl 19 you'll spend an additional 830 IP (again, same 2 completely unique pages, no replacements assumptions including of the tier 1s). If you start a new account, get the free IP boost from securing your e-mail thing, and play 1 game that day vs bots and win, then do the same the next day and the one after, those 3 games alone will pay for your entire reasonable tier 1 & 2 rune purchases and more.
