I wish they would bring back incomplete base forms
I've noticed something with Heisei Phase 1 Riders vs the more modern Riders, going between Kuuga, Den-O, and Kabuto vs. Zero-One, Geats, and ZEZTZ for example.
They got rid of Incomplete Forms.
Which, imo, does kinda suck, I get that it's for marketing and budget reasons that the Rider should get to their base form ASAP, but I liked the plot relevance of having a form for an episode before base, like Kuuga using Growing form at first in Kuuga(and >!the part where he gets brutally injured)!< and Ryotaro not being possessed by an Imagin leading to Den-O's Incomplete Form at first.
I wish they could find a way to bring them back, mostly bc I really like watching Riders grow the resolve to be the hero of the story, or in Kabuto's case, Deliberately holding back until he uses Cast Off on-camera for the first time. It's such a neat concept of introducing the main Rider that I wish would come back one day.
