Just realized something
The difference between between tier 2 and tier 3 runes is less than 1%! This makes tier 3 runes highly unfavorable!
I remember back in S2 when I started, one of the first things an experienced player told me, (after he told me to stop having 
as a full build on 
) don't waste any IP on tier 1 or 2 runes because they aren't cost efficient, wait to level 20 to buy tier 3 runes.
When he said it, I didn't know what a rune was and I had 0 points in my masteries.
Now here I am, years later on a new account, 18 rune pages short, no longer owning every champ, thinking... why the heck would I buy tier 3 runes!? With the exception of (what is now called) "lethality" and magic penetration, runes don't really have that much of an effect on the match anyway.
Unless you're a jungler, then flat armor (and attack speed for certain champs) runes work miracles.
RIOT, stop the shenanigans, get rid of tier 2 runes, make tier 3 runes cheap, then sky rocket the price of rune pages for all I care. I'd have no problem fleshing out $$$$$ for rune pages when I know I can afford all the runes.
Honestly, just reached level 30 and I'm already $250 invested, getting the bare minimal champs I like to play with (with Camille being the new addition).
