Welcome to... The Offseason (and possible sandbox)
I think this would be a nice way for Kabam to give us a break from the stress of doing well for AQ/AW. I understand Kabam may have something in store for the break that's coming up, but this would be my iteration and I hope they would take it into consideration. This would be a 2-4 week break from these game modes, however for AW you can still do a scrimmage with another alliance, get rewards (juicy 6* and 5* shards), but it will NOT affect your war rating or your placement for the following season. As for AQ, maybe just shutting it down for a while would be nice (I don't recall what Kabam has done when transition from Season to Season in AQ).
I would also propose introducing a Sandbox Mode where we can choose whatever character we would like to fight, change the signature ability of that character, and even add different nodes. I think this would help Content Creators to figure out tips and tricks to share about fighting certain characters & it would certainly help the players to fight a character that they have have trouble going against, especially in AW.
What are your thoughts?
