Why are we limited to 2 rune pages?

At least that we can edit, that is. It makes it stupid to try and customize it for each champion in champ select, even when it's a champ you know. I don't want to have to use the preset when I try something different, or get autofilled, and I don't have the time to sit there and figure out what each and every little rune is in champ select. I don't want to pour money into this game, and this just seems like a cheesy way of getting more revenue. I would prefer having any amount of pages, but if I had to, I would agree 4-5 is appropriate if we absolutely have to pay to get more. Also, to be fair to those who have bought rune pages before Runes Reforged, give them some skins or extra BE or something along those lines. What do you guys think?
