But that's pretty much the case with every toy and the reality of being a toy designer. Every figure has a tight budget which they have to stick with. If they'd made the toy according to everything that Hasui wanted, then it would've blown the budget and the toy might cost $500, which wouldn't sell in commercially viable quantities to justify the cost of development and production. Transformers has been this way since the 1980s, it's nothing new or surprising. e.g. one of the prototypes for the Diaclone Battle Convoy toy (original Optimus Prime) featured longer antennae, longer smokestacks, the "Freightliner" logo sculpted on the actual front grille, as well as being able to attach the rifles onto the shoulders. These features may have been dropped in the final product due to budgetary reasons. We know that Ginrai was simplified for Powermaster Optimus Prime to conform to a lower price point (similar to how Combiner Wars Computron is a cheaper version of Unite Warriors Computicon, but is also notably cheaper), and the
prototype for Godbomber was also a more complex toy - being less of a partsformer than the final product - but Ono Koujin has stated in an interview that this was abandoned due to budgetary reasons.
