After a week of playing with masteries being free, I have come to REALLY appreciate how fundamental this aspect of the game is - and yet underutilized (at least in my own playing experience) due to the paywall.
I believe that once the initial investment of getting them unlocked by summoners has been made, switching masteries should be COMPLETELY FREE.
This past week has been SO ENJOYABLE as masteries were an integral AND dynamic part of my play strategy - instead of the CHORE / PAIN that it usually is!
To be able to freely experiment with, and adapt mastery setups according to play mode would tremendously add to the FUN FACTOR of playing MCOC.
So Kabam, please consider making the MOST, BESTEST* PRO PLAYER MOVE by making switching masteries free.
Please.
Pretty please?
