I never questioned that making games is expensive, time consuming, and clearly a labor of love. And I think it's unrealistic to make a statement like that and assume it means things don't get overlooked or deprioritized as a principle. Brilliant people make mistakes and forget about nuances.
You're absolutely right, I don't like the decision. I think it's visually inconsistent and pointlessly bends universe rules for little to no benefit to the player. If there's a great justification for why this takes place and benefits the player I'd love to know, but it isn't existent in Halo 4 where this issue took place before. Maybe Halo 5 will offer the answer.
I get it. I'm not saying that 343i doesn't have long, protracted debates about lore, character design, or consistency. But I, as a long time fan of the series, often notice little inconsistencies here and there. And while they may be readily apparent to you since you work there? It doesn't exactly mean anything to me or anyone else outside the studio. I wasn't there. You could've been the very person sticking your feet in the ground about such a decision, attempting to keep inconsistencies at bay. But I wouldn't ever have any idea. I can only go off what I see, and I see inconsistency. Empathy works both ways.
