Number of masterypages

I know you're changing this system, but there is something I'd like to point out. I don't get it why there is limited amount of mastery pages. I hope you don't have some stupid explanation like Blizzard "Because players would be overwhelmed" and I don't think it takes a lot of place at your servers. From my point of view, I would have a mastery page per champion i play and for some multiple. It's quite frustrating to have to change theme every time I try other champions. Of curse if you change their cap to for example some big number like amount of champions times two, you will have to ad a searching bar in champion picking screen. Please take it into consideration while implementing new runes system. Thank you.

(Oh and you could use the section like "feedback" that doesn't require to complete 5 pages of form)
