Not sure if this has been posted yet or not, but it would be nice to have two things. The first being random I generally don't care what demigod I play and if hidden isn't put in this will dissallow people from reaction picking.
The second is hiding the demigod the opposite team picks. If I know I'm goign up against a good team I always reaction pick if tehy pick a certain group my team will pick a good group to counter it. It would be nice if it was all just hidden to prevent people pregame from knowing what you're going to be and reaction picking.
Just ideas though.
