Considering that Emet’s masteries are absolutely ridiculous to achieve may I just suggest this:
Tier 2 Respawn Beacon: Allow multiple points per match. Being forced to play 10 matches and use the thing twice is torturous. Given that in any real match playing 10 matches would likely take 150 to over 200+ minutes which is three hours or more.
Tier 3 Masteries: In general, lower these, these masteries are astronomical in my eyes coming from the guy who masters everything right off the bat. It seems that at launch masteries are unrealistically high and will take a multitude of hours or even days of grinding to get or months to get doing it completely legit.
