Not Enough Mastery Choice (I take the same page every game)

TL:DR make more masteries RIOT

With all my games I run thunder-lord over any other choice of master keystone at the end because nothing else gets me as far in the game as this one. Give me an option to compete with. even death-fire-touch doesn't do as much, I can take Teemo shrooms and they proc thunder-lord and zap a target for more damage than (DFT) can put out. RIOT cmon really thunderlord is out of hand and DFT needs some love. But back on track here the masteries need more choice rather than 2 on each level make 4 to choose from on every level. so that the game is more diverse and has some thinking and skill in to the pre-game.
