Where are the Scarabs?

I Know Halo 4 has been out for awhile now and I have the Limited edition! Although this Guy has just realized there is no Scarabs in Halo 4! I wonder why?

A bit difficult to maintain a huge fleet of ships and machines like Scarabs when your whole species existence has been for war… Elites aren’t exactly the best engineers or doctors, Jul’s ragtag fleet of backwater Sangheili even less so. They’re still out there, just not as common.

They brought hundreds of lecters with green scarab beam they are a flying scarab pretty much They kinda feel like the halo 2 transport scarab when you board them inside

scarab is an invasion and large scale warfare tool.

the warfare in halo 4 campaign/spos is very small scale. a scarab against a squad of spartan ivs or a lone master chief would be pointless.

it was replace with this Ugly thing.

Well in Glasslands they did say that they had a severe shortage in…everything, considering the lack of engineers.
