why are the the BTB maps so much smaller?

I know that the maps were made in forge, and they’re still well made and fun ,but even having spartan abilities, it seems way more compacted. there’s no warthogs on guillotine and why didn’t they make the doors so that you could open them on deadlock, is scripting not returning or not implemented yet. Like I said, the’re still fun, but it seems like there’s a lot of things missing and the maps seem generally smaller. the whales on guillotine are a nice touch though.
