Halo 4 had space combat, did it not. Negating point 18.
Halo 4 also had a 'real' campaign- it happened in lore and it exists on the disc
There is a UI that shows who is in the party. Press X.
The falcon can't really be used on the maps- maps are too small and one forge is in space with another underground. Perfectly logical to remove something not needed.
Vehicles are worth piloting also. Mantis, Guass, Scorp, Wraith, Ghost come to mind especially
I don't paticularly like custom loadouts, but understand descisions behind them.
Explain how Halo 4 explosions look like 'confetti'
It is not nearly impossible to level up if you don't play matchmaking in all your spare time, I don't see the problem
DMR was the only headshot weapon, alongside rare needle rifle. It can't be OP with itself
Brutes were hunted nearly to extinction by Elites, the rest devolved into Tribes; TL;DR- the brutes are in no state to fight anyone else
BTB maps are fairly crap, give you that
Invasion is a good GT, but maps are not good for it on 4
Assault is made very easily on Grifball GT settings (look in my fileshare)
Boltshot is very good now its been nerfed. I rarely get killed by it.
Oh, and that wasn't in any order
