Higher exp though? Do you really need exp?
It's just the fact that it's already there, but so piddly and not based on performance (maybe the latter might make it "abuseable" but I don't see anyone getting especially good EXP either way so I doubt there'd be harm in it) that there's room to increase it. It might not be that enticing, but 500 may as well be 0, so they can make it bigger without a fuss.
