Go play Halo wars 2.Well, Halo 2 has a whole mission where the ODST are tasked with securing a Landing Zone for Pelicans, which is the UNSC's mainstay DropSHIP used to ferry around Warthogs and Scorpions on an EXTERNAL cargo hard-point.Well how do you know scorpions and warthogs can't be dropped by a pod of some kind. There's a lot in the halo universe and yet there's so much more that has yet to created/hasn't even been covered yet, who knows a vehicle pod may become a part of it. (note I have left out the mongoose, this is because during Red vs Blue season 9 or 10 - I think it's 10, Tex had a 2 wheeled mongoose styled motorcycle delivered via drop pod and well a mongoose isn't that much bigger than than the cycle).
That's kinda the issue, if you can bring in Pelicans or other large landing craft, you don't NEED the Drop Pods since you don't need the small profile to dodge heavy anti-air defenses.
While a Pelican air-lifting a Scorpion would make an AWESOME set, I think that kind of part count could only be done by the Signature Series.
Now, you'd have a much better argument for the Mantis, since in-game it's inactivated pose looks compressed enough to roughly be Drop Pod sized, but I don't know if the Mega Bloks incarnations can actually fold up like that.
Scorpion's can be dropped from orbit without a pod.
