Here's some things I think would be cool:
1.It would be cool if they got the Hageman brothers (the original writers) to write a new short or season.
2.A lot of people say this but A CMF would be neat
3.I would be excited if we got a Ninjago advent calendar
Honestly, I just hope they do something more. The sets are cool, but I feel like their should maybe be more. I like your ideas!
