As somebody who used to always just have 1 mastery page and would edit it every game depending on who i'm playing, it's really annoying seeing these 5 preset rune pages in the way.
They're letting you delete them soon..
Riot is planning on adding the option to hide the preset rune pages in the near future so you don't have to look at them. Possibly even in the next patch. I don't think you'll ever be able to delete or edit them though.
I'm pretty sure you have stacked enough BE for a couple of Rune Pages. It's still pretty laggy & lengthy to edit on just that one Rune Page itself during champ select.
I wish that you could select a keystone and it would give you a pre-selected set of runes to go with it rather than the five pages, then You could have one preset tab and however many pages you have made.
