I try to understand phenomenon of tanking, but I can't.
If you feel you'll struggle in the league/cup this season, why you don't try to test another formations, experiment with mentality and arrows, etc. ? It's nothing to lose, in worst scenario you'll just lose a match. If you tank, you'll lose many matches. So what's the point?
In my oppinion, if you fight bravely, you always have a chance to get underdog win, so at the end of the season you'll have more money, tokens adn your players will have bigger boost. And after all, what's with satisfaction? Is it really cool to beat team which start league and is few Q weaker than your team?
