At least Bungie was smart enough not to put the banshee on the map(at least in BTB). I agree with the user who said it wasn't built well for walking on foot, its a scary map for people without snipers. While many complain about the amount(or types) of vehicles in the map, I believe this is the only map where you can see real vehicle on vehicle combat, something very scarce in Halo Reach. Almost all default Reach maps lack vehicles, and most if not all user-made BTB Forge World maps are atrocities in terms of design for vehicles and in general.
DLC maps may have some good vehicle scenarios, but even they are nothing compared even to Halo 3 maps.(Halo 3 had Avalanche, Valhalla,Sandtrap.) Anniversary had some nice scenarios as well, but they were too small for anything seriously fun, besides a few Ghost fights on Ridgeline/Timberland.
Hemorrage feels like the last place for people to really enjoy vehicles. I still dislike it somewhat. I was always confused as to why Bungie didn't remake Valhalla, but remade Coagulation. So I wouldn't mind it being removed, as long as it was replaced with something as active with vehicles as Hemorrage was.
