I've spent over 40,000 IP on runes
MS quints = 2050x3 AD marks/armor seals/MR glyphs = 205x9 per category AD quints = 512x3 AS quints = 1025x3 magic pen marks/hp per lvl seals/cdr per lvl glyphs = 410x9 per category AP quints = 512x3 armor pen marks = 410x9 dual pen marks = 820x9
and these are simply the runes you need for mages, assassins, and ADs to be competitive over the 4-5 seasons I've played. It says nothing of the armor quints, scaling armor seals, flat AP or scaling MR glyphs I've bought on top of numerous others.
I don't care if I get a single point back it's a bad system and if it's addressed (and fixed) for newer players and it gets more people interested in the game then it's worth it.
EDIT; this doesn't include rune pages, of which I have 13. I got at least 3 from 2-for-1 sales.
Also, for the people that say that's a trivial amount, that's just for optimal setups for mid/ads/adcs over the years. I added up the total just for you guys.
It's 95k. Not as much as the people that intentionally bought stupid/severely weak runes but still a very large percentage of the game going toward laughably small in-game bonuses.
