Increase XP rewards or decrease level requirements at higher levels

The level requirements are absolutely insane for this game considering how little XP you receive from normal play. My suggestion is double the normal gains just to make it less punishing for everyone. That way the double XP events actually make people want to play during the event. The later levels should still require a fair bit of XP but at the moment it's beyond the patience of anyone.
