The New Rune System Seems A Lot Like The Old Mastery System But More Limited

I was looking at the new rune system, trying to figure out which runes might be good for certain champions, that's when I noticed something, the new rune system, it's exactly like the mastery system, just a more limited variation of it. If you actually take a look at it, it's just a larger mastery system, where instead of making as many pages as you want, without having to buy more pages, you have to buy more pages, or alter the two free ones that you get before every game, and hope that you get either of the two roles that you set your pages to.
