I wish there were more mechanics that made it literally impossible to just 'leech' a fight. That way, mediocre players wouldn't be able to get past the harder content by simply buying it. Now don't get me wrong... I'm not talking about the 'morality' of selling or buying wins. I'm talking about the 'skill check' these fights are supposed to provide. The harder fights are supposed to force the mediocre players to learn to be better... but if you can just buy the fights, there is NOTHING forcing you to be better. I would argue that Twintania's DPS checks and mechanics are so tight that you can't leech it (has anyone sold Twintania wins?), but Turn 5 is going to get nerfed with the next patch, so there really is nothing to force mediocre players to learn.
