The main thing is, in more than 70% of the times, tanking is just a symptom of a bigger problem called associations. Personally I wanted to tank this season not because I wanted to gain advantage, but more about extending the life of some of the recommended players I bought in the last 2 seasons, because I need to get the value of the tokens I spent.
I honestly couldn't do it, tanking is boring for those like me who play for daily entertainment, no CL, no league and just the cup to hopefully kill the boredom.

My main concern in drastically killing tanking, is removing the ability for struggling players to be competitive and gain resources. Plus there is a big reason for tanking that no one mentions, finding new opponents. this game gets boring by having the same teams season after season.
