Feature Request: Associating Masteries with Champs and Gamemodes
Pretty simple: 20 pages of masteries is a lot to scroll through to find the right one at the start of the match; 20 pages of masteries is not enough to cover all the different champs I've got unlocked, let alone their different sub-roles, or different builds for ARAM / Twisted Treeline / etc.
Basically, I'd like it if it worked a bit more like the item pre-set building option; where I can make as many mastery pages as I need - so I don't have to compromise a mastery-build for any given champ on the grounds that the page is being shared with other champs - and so the only mastery pages I need to choose from are those I've assigned to the champ & game-mode in question.
Nice, simple quality-of-life improvement; means I'm not compromising my builds against people who have focussed on a few narrow and very specific game-modes / champs with their builds.
