We have temporarily brought Tribble down as we prepare it to be used for testing new code. We expect Tribble to be brought back up with a new build in around one week or so from this post.
When Tribble does become available again, it will not be to test Romulan gameplay. We do have a testing plan for the content in the Legacy of Romulus expansion and will provide more updates on it as it becomes available. In the meantime, the upcoming patch notes for Tribble will include further details on what will be available for testing.
So Tribble can be readied to test realy advanced changes.
We are not getting 2 test shards permanently.
Redshirt exists when Tribble is in season testing not because of the so called "advanced things" but because Tribble is being used to test the season things but of course this happens about a month before it hits Holodeck so for weeks they need a testing shard FOR Holodeck changes.
Today is the 26/27 so we have about 2 months before the expansion hits, now thing is with season-7 we had a lot of things locked off and we need to proper test things of the expansion and its not "advanced" things we need to test, we need to test level progression for starters, we have less that 2 months for that.
Well downloaded the patch for red-shirt and it didn't work? It loaded ok, then when it gets to the character selection screen its just a black screen with the mouse pointer! Holodeck and tribble load fine.
I imagine that they will hold off testing the "story content" of LoR as late as possible. And I won't be surprised if it doesn't appear on Tribble until after the release. They won't want spoilers as to who the new enemy is until the actual launch.
But I expect we will get to see the improved UI, trait changes and Tholian Repulatition systems (plus Tholian STF) first.
When the testing / release plan to Tribble is posted, it will probably be a good idea to list what won't be appearing on Tribble before the launch date. Because if the new / converted from Fed / updated KDF story missions aren't going to appear until after the launch, the forums will once again be full of posts of KDF hyper-rage.
