As a disclaimer, I've never taken any courses on game design, nor have I read any books (though I have been told that Characteristics of Games by George Skaff Elias, Richard Garfield, and several others, is excellent and every aspiring game designer should own it). I have played my fair share of games and studied many others on my own time and listened to a plethora of critiques and reviews, for what that's worth.
One idea that I've heard espoused over and over again, is that a card or board game (really any game, tbh) wants rules and mechanics that encourage the kind of gameplay you (the designer) would like to see / want the player engaged in. Seems obvious enough, but if we look at the 'Masteries' Riot gives us, we find mostly raw stats with a few interesting conditional effects here and there. So what kind of game play does Riot want to encourage? Well, I would think peeling for your allies, focusing the same target, contesting and taking objectives, using the minion waves effectively, scoring kills and assists, warding, etc, etc.
So this is my attempt, similar to my Summoner Spells Redux, at making the 'Masteries' a bit more objective-focused, team-oriented, and skill-based, rather than the raw stat pumps Riot has been so fond of since the games inception. I've also rebranded the 'trees' to suit the new direction I've taken things. I don't know how these abilities should be weighted within the current 30 point distribution trees. I not sure it should.
I'm going to say that each player has 7 slots or points. You can choose any mastery from any pool, mixing and matching as you see fit. You can go 4/2/1, 7/0/0, 2/2/3, 1/3/3, etc. leaving a ton of possibilities. The idea is that you can really define your play-style and customize your champion to suit your particular role and idiosyncrasies. For me, that means supporting with Shaco and incorporating masteries that play with vision in unique and interesting ways! (Hopefully.)
