I think he is assuming Halo was a game where the grunts were good guys and only the elites were evil enemies, you know, because in real life the elite are always so persecuted and made out to be the bad guys by all the lazy poor people. Thats why he says "grunts vs elites," not realizing they were both antagonists as members of a religious zealot alien empire (which was actually coded in such a way as to at least somewhat play into Islamophobia) being fought by the righteous American special-forces-coded protagonist. Seriously I bet he thinks it was a class war styled video game and he's "guessing no one wanted to be an elite" because he thinks they were probably the baddies, made that way by woke game developers to malign the hard working ultra-rich job creator class who the dirty proles will call "elite" as a pejorative.

Or I dont know, maybe I'm way off and that's not what he's saying, but knowing how this bootlicking wannabe-intellectual chud has presented himself in the past as a warrior for the persecuted rich, it seems to fit with this word salad of ignorance and cringe.
