Since the only reason that you would go into the CW in Arcade is to get the prize wheel(no one misses this), Danger Room(hard and pays out well, but I bet even new player from the mission update haven't heard of this) and the Scenario Room(The missions give out more info on lore). So to improve this:
Hall of Heroes: Exclude 5* along with the already excluded Boss reward lines Recipies. This would be good as it would allow people to do Arcade levels more.
Next, make the boss levels payout less in mission mode that gate mode and the tokens be two max.(wait, they already do!!!! But the token rewards should be two max, if not 1)
Dms should have high payout.
Warden should be in a mission whare he explains the gates and the Arcade tab. Kinda sad OOO negleted that.
Finally, Scenario rooms should be more exiting and informative on the lore. Minibosses prehaps?

I too, am in favor of the clockworks. Although missions should also be viable.
