Mastery System is kind of flawed
So recently I had this match where an Akali was trying to get an S rank to get to level 7. If we had skirmishes where we could win if she helped she would just leave to keep a low death count. When we needed her to fight in team fights and group she would just farm because she needed the S rank. And even when I tried to farm Jungle camps when I would start them she would just ult them and take them. We eventually lost the game because she left our jg and I(our mid) to 2v2 when we could've easily won if she had helped. She just watched us from the brush. I don't completely blame her because I have played like that before just to get an S rank. I just feel like the system makes you play extremely selfishly which usually ends up in a loss. Usually ends up you do good because you wouldn't help in fights and your team feeds because you didn't help. Anyone else think the system is flawed
