Realism > style.
In your opinion, yes. And while I definitely love realistic figures, I love stylized toys just as much. Here's a selection of Marmit figures from my collection.
While most of them aren't realistic, I still think they're great toys that just happen to go for a different style. I know lots of people who love toys like these. Obviously you don't, but it's worth mentioning that this is a very popular style among adult collectors in Japan, whereas Bandai toys are primarily intended for children.
If Bandai cant add more then the standard 6 axis, that's their fault.
And of course it's obvious to me that you fail to realize that limited articulation is a decades old design preference among toy companies in Japan who put out kaiju figures. This dates all the way back to the Marusan figures of the 1960s and continued through companies like Bullmark, Popy, Yamakatsu, Bandai, M-1 and modern companies like Marmit, Gigabrain, the current Marusan, Pilot Ace, Toy Graph, X-Plus, CCP and others. In fact, the only Japanese company I can think of offhand who has put out "action figures" of Toho kaiju is Kaiyodo through the Revoltech line, which just started this year and is the exception to the rule. 5-6 points of articulation on vinyl Godzilla toys is the norm in Japan. It didn't start with Bandai and it's continued since Bandai. Blaming Bandai when this is the predominant style of Japan vinyl kaiju toys for almost 45 years makes no sense to me.
