Important Feature Incorporation
This is a very simple concept that I've waited to be implemented since I started playing League: the ability to reorder mastery pages. I like to keep my mastery pages alphabetized so they're easier to find during champ select, but this is difficult when I make a new mastery page and have to delete all of my existing ones and recreate them.
People have organizational preferences, and this feature would make those dreams a lot easier to actualize. Please consider incorporating this into a future update.
