V. happy if the Brutes are back, please turn Halo back into a political space opera rather than LITERALLY FUCKING EVERYONE vs Humanity (who are now all Spartans, for some reason) again please.
Halo 2 & 3 were great because you fought alongside Humans, Elites, Hunters, Grunts, Jackals, ODST, Sentinels, and even the flood, depending on the vibe at the time; heck, you even got some sweet Covenant vs Heretics action. The best combat scenarios just descended into a giant fuckest: everyone for themselves.
Retcon Palmer, Del Rio, Lasky, the Spartan 4s and all the other idiots.
Also get rid of all the 'Master Chief human story' bollocks. Fuck off, you can't pull it off. Stop trying. I've seen a better 'human story' in the very hungry fucking caterpillar, at least the caterpillar got some exposition.
AND CAN WE HAVE THE FUCKING CHOIRS BACK, PLEASE? IS IT THAT MUCH TO ASK?
