I think they should make a gremlin boss, I know the roarmulus twins is the gremlin boss but they made that, I kind of want an actual gremlin boss in the flesh so shadow weapons like Acheron and faust can become more useful, and the gremlins were the ones that made the clockworks (With the help of the core possibly).
I also think that they should add in other stuff in spiral knights so it's more fun, don't you think its boring, continuously doing the same thing all over again running Vanaduke and Jelly King stratum just for crowns.
all bosses do no share the weaknesses of the monster family they seem to represent
i think king Tinkinzar is in the core and is going to be a boss if they ever release the core
