Why do we need carriers in Discovery?

[Epo]

I can propose a hypothetical scenario in which carriers act as a portable jump gate, providing the snubs with the access to the field, when they use specialized military gates.

This can be imagined as a jump drive concept turned inside-out. The ship itself provides a mobile exit point with the stationary gate on the other side. It could use fuel, have or have no restrictions on jumping, being in vulnerable phases, and so on and so forth, the field for balancing in my opinion is wide.

That's what I and Thundered already talked about.

it was planned to make it possible to teleport from station to Carrier with Docking Module.

Or maybe jumping to carrier equiped with a special jump drive? As normal battleships can use docking modules as well and making simple JD mountable only on special carrier-only slot would be easier I think.

EDIT: Also +1 from me for something like this.
