It wasn't perfect, that's for sure, but I don't think the problems were anything that couldn't have been addressed using the tools they have at their disposal. Coagulation in Halo 2 worked beautifully in Team Skirmish (4v4), and the problem is that Hemorrhage is a terrible remake. Important details were wrong, such as the rocks at the tele exit, and the location of the exits for that matter. They said it was a direct geometry rip from Halo 2, but this isn't accurate. It's not possible to make the superior Coagulation bases, which would massively improve the shotgun camping that exists now. My stance is that if a map that is currently busted can be fixed with some simple changes, then do that instead of removing it. Regardless, it filled a much-needed void in the playlist - vehicle-based objective games.
Edit: You know, I said last week that I'd have liked to see greater detail on what exactly the Objective changes were going to be in the update. If we had gotten the full list instead of a vague statement about fringe gametypes, the outcry might have stopped this shit before it happened.
