I see a problem there. Mata were just as cloney as the Inika. Hrm. For some reason, I don't quite agree with that, if only because the Mata had two stand-out variations (Pohatu's upside-down gearbox and Onua's hunched stature), as well as more varied weapons (with actual differences in structure and utility, rather than Sword Or Gun), while the Inika's variation was pretty much entirely limited to what pieces were used as opposed to how they were used. I mean, both were still pretty clone-y, and I definitely don't agree that the Metru had more variation than the Inika (since outside of varied molds, literally the only thing setting the Metru apart was torso length), but I don't think the Mata were just as clone-y, since their individual builds still had an element of diversity to them that the Inika simply discarded. I don't think sets necessarily need to be clones to look like they belong on the same team. The 2015 Toa all had shared motifs, such as their piston armor, similar tool aesthetics, and chest patterns, that drew them together visually as belonging to the same team, while still having varied builds with individual personality. For something like the Bohrok, where they're intended to be a literal swarm of identical creatures, I don't think being clone sets was all that bad, because yeah, it made sense. But for Toa, where individual personality matters as much as, if not more than, team cohesion, being exact clones of each other is more of a detriment than a benefit.
