I'm not sure if you are aware of the bug with Tinkers being able to use other heroes' abilities but i just went up against a tinker with the warlock ability and his board clear was insane. Here is the proof. http://imgur.com/WLCLUMn
Boss fights would be really cool in this game I can just imagine flying around in space while trying to dodge an attack or something having different phase for different tactics so you wouldn't get bored out. You could put one up every hour or so and 15m before it starts you can let them queue up. Another idea would be every boss fight has a specific class that has a special role in the fight though you would have to make a system to not have too much of one class
