Earlier today, I decided to play a game of LeBlanc on Twisted Treeline. With a KDA of 25/3/2, I managed to bag myself an S+. However, I noticed that I didn't get a lvl 6 Mastery Token on it (I'm a lvl 5 LeBlanc). I found out it was intentional, and I want to know, why, Riot?!
Pretty sure it was something like TT, ARAM and RGMQ all feature games that are faster paced and take less time. Riot wants levels 6 & 7 to be something to strive for that you achieve and have the highest amount of work put into it, so you can only gain them in a normal or ranked Summoner's Rift.
Because TT is not the main Gamemode.
Riot wanted to continue to funnel people into SR, so that they can continue to neglect non-SR modes. No incentives means no playerbase, which means no complaints, which means Riot can slowly shut down the other modes.
