I'm about to complain! Let's be honest here, majority of us are 'alright' with the boss spawner, but I'd have preferred it if they included some bosses that weren't already playable characters and in Toybox take over and so on. How amazing would it have been if we'd have gone to spawn a boss and the option to include the likes of Jafar, Ursula, Queen of Hearts and so on! Would give us the chance to make some fantastic Toyboxes! Especially if Jafar was included with all the Aladdin content we have.
I think at times they develop these ideas but miss the mark with them. Hopefully we'll see more added to this soon
