Champion Mastery
Why does it seem that champion mastery is 100% based on creep score? I have been trying to get rank 7 on Kha for a while now, but it seems pretty much impossible in the jungle. I had to play toplane Kha just to get to rank 6. As top I can AFK farm and get very mediocre scores, and more often than not get an S-. As jungle I can get amazing scores and solo carry my entire team, but get nothing but A- because Kha sucks at clearing the jungle and it is much more efficient to farm champions (while that 4/2/3 Ashe on my team gets an S just because she had 250 CS).
Another champion I play, Kindred, took me 6 games to make rank 7. 3 of them were S-, 2 S, and 1 S+. I didn't do particularly well in the S- games, but Kindred is so good at clearing quickly that I can almost guarantee an S with the amount of CS i can get.
I understand that skill is somewhat shown by getting lots of CS, but that is only true for certain roles and champions...
