Interesting! Thanks for sharing this bug. I'll put it on our backlog to fix.

Yes, Simplicity definitely needs a buff! It does give 2 mult per empty slot so it's a max of 8, but even then it's not very good for a Rare. I was just looking at some of the analytics today and it is the Rare with the least win rate in the game at the moment.
I'm glad you like wandering around the room! At the moment there is not a reason to do it or not. In the future we plan to put metagame stuff there. Things you unlock, achievement trophies etc (all subject to change, don't quote me on it, these are just our current plans)
