How do you deal with an extremely uncooperative shard member?

So he consistently waste crystals to stay at the top.  Using them all the time means he has to acquire more crystals (good for EA) all while playing within the parameters of the game and you want them to do what exactly to satisfy you?  Should he just cheat or bow down to you?  EA has more pressing matters to address in the game, like actual cheaters,  than someone playing within the rules.
