This. I feel there also should have been more exposition of the prince and the "war" in general.
In the book Edmond is arrested for conspiring for Napoleon while in the show he was arrested for conspiring in the murder of the prince. In the book, it made more sense in context with one's basic understanding of world history but in the show it simply started a "war" that Morcerf, Danglars, and Villefort used to further themselves. The "war" and the significance of the prince are not fully explained and do not become relevant until the last few episodes leading to a bit of confusion, especially to those of us who have read the original novel.
I have to admit though, that using mechs for the duel was fucking amazing. Seriously, everyone who worked on this should be the only staff Gonzo has because then we'd know they wouldn't shit things up like they usually do.
