I have been thinking about the ARMS character lately. While I would prefer Twintelle, Dr. Coyle, or the "Bowser Jr./Hero" situation (simply for the possibility of multiple ARMS amiibo) I think Im rooting more for Spring-Man/Ribbon Girl combo. Same character slot 4 alts each. I just feel Smash should just stick to tradition and make the "main" characters the first choices. To me it would feel odd if say idk Mechanica was chosen before those 2. It would be like adding Bowser before Mario, Diddy before DK, Falco before Fox, etc.
As much as I love Twintelle, Master Mummy, and Dr. Coyle. It would feel weird adding one of them to my amiibo shelf before Spring-Man and Ribbon Girl. That being said obviously I love 80% of the ARMS cast and would be happy with those 80% and indifferent towards Byte & Bark, Mechanica, and Misango. Everyone else I really enjoy though and wouldn't mind.
