like I said before there is a bug you can exploit to farm lvl and mojo ( from now on) which I'm pretty sure some with high mojo and high lvl might have use. Using this bug you can do more than 30 fight by hour. Pretty much, it's you open the game on multiple browser and in incognito (also if you use multiple computer it work) for each browser and each incognito you can use all your fight point. As soon as I found it I mention it but there was no return on it. I don't know if the bug is still in the game.
