Vehicle Tiers?

[Marinealver]

Just wondering if they are going to bring back the Vehicle Tears with a Tech-facility DropShip Center that they used to do.

In the old Planetside this is what I considered the tiers

Tier 1 Aircraft and Vehicles that can be produced at any base.
(Though I considered that Wasps and SkyGuards should have been in this one.)
Tier 2 Aircraft and Vehicles that require the Tech Facility to aquire.
Tier 3 Battle Frame Robotics and Aircraft that can only be aqqured at a DropShip Center.
