I'm not a fan of the Megazord for this series. While I like the Lego-like aspect to it I don't like the combined modes. They look super tacked on. Like its not one zord making up the arms and another making up the torso. It's more like they have just strapped the other zords onto the main one as weapons.
Nothing Hasbro can do about it but pick another Sentai to use, but some of the Sentai recently I don't think would have appealed to the West. Maybe Lupinranger VS Patranger, but that was very different as it was 2 teams of 3 and they were sort of against each other as a cops vs robbers sort of deal.

Oh and if you thought 10 Rangers in Dino Charge was a lot, look into Kyurangers. They had 12 in total, most of them being there from the start.
I do like the suits from that series but the zords look like trash. I can see why Saban/Hasbro skipped it and
