I liked the Apex during Alpha, and I like using it now. I never really understood the complaints.
The real killer for me is that you can't use Apex to/from a fleet carrier. I know, I know, there's nowhere to disembark, but there should be, even if it's a copy/paste of the little area Engineers have on their ground bases.
And team mates who die on settlements should have the option of respawning on a carrier so they can Apex back to the action.
Also, if I want to buy and equip a new ship, I'd like to Apex to the shipyard, buy and fit out the vessel, then fly it home.
