The new runes?

So I was able to get on the PBE a few days before the new runes officially hit the rift, and I could have sworn during that short period of time I saw the max cap for custom rune pages was 3. (correct me if I'm wrong) Why is it capped at 2 for the alpha client? Again, if I missed a note, please correct me. 3 was a very fair number.

But more to my other point, not that I'm being ungrateful for these new impacting runes, but why are we only allowed such a small quantity of custom rune pages? Sure the presets are nice to have around, but I don't want to make and edit a new page every single champ select if I wanna try out and play around with runes and champs.

If anything, the preset runes (keystones and all) should be editable. I'm getting a little tired of having to make a new page. (I main support and play champs like taric, lulu, sona, and off-meta supports like illaoi and maokai, so 1 page really wouldn't fit for all of them). I want a similar system to our old masteries and runes; not uncapped, but a limit of 7-10 custom rune pages would be nice to have some versatility.
