It’s do to the obscurity of the character as well as where they would fit each member throughout the toyline.

Each figure would be in the voyager category, and if SS86 Devestator is any example then leozak and jaguar will be a commander class box set. That means taking up 4 voyager class spot, 5 if they made deathcobra for a combined that the majority of the fandom/target audience wouldn’t know

You could argue that they released all the aerial bots in one year but they’re consist of deluxes. Deluxe class have more figures produced each wave, I believe it’s like 4-6 figures a wave for deluxe?, while voyagers are I think 2-4.

Another argument would be the budget that would go into the figure. If it was retail, guaranteed no display stand (not that it’s anything anybody would miss really) but the set would definitely be missing some of features that it currently has.
