They could also disable mission rewards (skillpoints, items, emblems, ...) on Tribble to further disencourage people to see the testbed server as an alternative to Holodeck, by the way.
Can't do that either. As some missions need to have their skill points, emblem amounts checked. This has been proven before where our feedback has been based off rewards.
New ships of course should be for free on tribble. It allows us time to go through and make sure the bugs are cleared out.
However, I don't agree that we need to test out costumes, bridge packs etc. Costumes are seen running around the same day they come out on holodeck, as for bridge packs it's the same thing. You can easily ask in ESD if someone got it and if they don't mind you taking a peek.
