My first impression of that strike was that it was poor. Easy Easy Easy, bullet sponge, floor drops out, bullet sponge, floor drops out, bullet sponge. I never actually completed it. I really hope they have new interesting mechanics in the game, and not defend ghost while it opens a door.
I'd like bigger fireteams, where they have to split up to accomplish an overall task. I'm sure it will be a laugh along the way though.
