[i]"There was honor in our Covenant once, and there shall be again!" -The Storm, Halo 3[/i] [quote]He didn't say Humans and Covenant. And the Post Halo 2 part of GoO was still in the earliest stages of the Great Schism. During that time, yes, Sangheili used Hunters and Grunts as Arbiter did in Halo 2.[/quote]You need to keep in mind the context of the situation for the player. It'd be rather confusing to hear that the Covenant is on board when we just defeated them. Those additional forces that sided with the Elites, they aren't just going to disappear, which is what you appear to be claiming. [quote]However, there is no proof that during Halo 3 it was anything more than Elites allied with humanity. And if there were more species, it had to be such a negligible amount that they didn't get mentioned in and "during halo 3 lore"[/quote]There's also nothing that outright says no Unggoy, Kig-Yar, Yanme'e, Lekgolo, or Huragok weren't present as well. I don't deny the majority of Separatist forces deployed on the Ark were Sangheili, but that doesn't void the fact the UNSC technically considered them a Covenant faction, and as the quote above shows, even Thel considered that as well.
