Without random ordnance, you'd be playing the same game as before, except your casual friends wouldn't have to ask you where Rockets spawn or why we're camping at this one building over here. They'd already be at that building fighting for Rockets because the game told them shit was going down. As well, you wouldn't have to do "map walk-throughs" or pay such attention to the clock.
I know, it feels good to have knowledge no one else has and kill them with it, but something as crucial as where and when Rockets spawn in a mode about getting the most kills? That a Halo game hasn't introduced that knowledge to the player directly before Halo 4 is surprising. It'd be a lot like playing King of the Hill without waypoints or an announcer saying "HILL MOVED".
While I never heard of anyone complaining where power weapons spawn among my casual halo friends... I agree that a system of HUD waypoints, maybe even a bit of warning would be better.
I was saying ugh that you used antiquated as a word to describe Halo's old design. Made me cry inside.
But even having a 15 second or so warning for random ordnance is kinda meh. I'd much rather know rockets are going to spawn HERE in 3 minutes.
