I feel you, bro.
For now I'm trying the best I can with my three teams. Two of them can probably finish at a decent place, mainly because other teams are tanking. One team may not even finish top-8 even if I try. So tanking is definitely in place here.
I made my decision not to invest anything in the game for now. So not but anything that costs real money. Not spend the 3,000 tokens I have in store. Not even power train my teams with the greens I have saved from videos, since it will not bring me any trophies this season.
If this situation lasts longer, I must conclude that this game is not interesting any more. And then I will quit for good.
