Supports and jungle tanks reaching lvl 6 and 7 masteries
I've been playing a lot of tank Skarner lately in the jungle, and I secure around 4 dragons on a good game as well as a boatload of assists, but at the end of the game, I will get a B+ at most because I didn't rack up a bunch of farm and kills. I just finished a game as Soraka at 0/1/18, with a very high kill participation, and I got an A. How the hell am I supposed to reach the level 6 and 7 masteries in these champions if you can't get an S by being a team player??? I understand getting an S is supposed to be very challenging, but I feel like right now the champ mastery system just caters to the carries who get 20 kills and 300+ farm per game, and not giving enough credit to the people who set up those hard carriers.
Thoughts?
