Some new objective types would be nice. This would definitely add some variety without the need for new gamemodes (although I still want that too). As for my least favorite type, I don’t necessarily have one, but I do agree with everyone else that delivery objectives are annoying.
I do have a favorite though! EV escorting is by far the most fun, but only on Chapel. I can’t wait for Dockyard. Although I’m fairly disappointed with how Dockyard’s looking, I like the long EV escort and multiple side objectives.
There’s tons of possible objective types I’d like to see added into the game. The difficult part is probably how to implement them without making them too similar to the current objectives.
EDIT: One objective that immediately came to mind is a “Destroy the core” kind of objective. If you’ve ever played Unreal Tournament (or even games similar), then you probably know what I’m talking about. This can be implemented in multiple ways. I could definitely see it as explosive mayhem where Arty, Skyhammer, Kira, Fragger, and Nader reign supreme. Would be interesting to be honest.
