(I want to start out by stating this isn't a guide, this is a question and I know little will answer it because this community is small, but hey, always have room for growth)
So I know the timing is off, but the next campaign event will be when I get the Event Campaign Reward. I have a Temporal Recruit, which is who I'm getting this for, and I am getting a Constitution-class vessel. I'm leaning towards the Temporal Light Cruiser but am a bit tempted by the MW FDC (Also, if anyone wants to comment on how good their equivalents are, I would be happy to replace a Constitution-class with a (captured) D7 or T'Liss.)
Constitution Miracle Worker Flight Deck Carrier: Has the best performance apparently. Also looks good, but the TOS one is a bit better. Also am a bit tempted by the D7...
Constitution Temporal Light Cruiser: The OG, Captain Kirk's Enterprise (also can equip TMP Skin, so yay). Looks great, and has good performance. Leaning towards this, although the MW FDC is starting to lean on me.
Constitution Mirror Warship: Not really enthusiastic about this, but I included the other ones so why not. Apparently has a really good trait but isn't full spec, which is a bit pathetic, considering its age.
(NOTE: I have no interest in buying the 10th Anniversary Pack. The only bundle I'm slightly interested in are the T6 Romulan Bundles (The Legendary Ones) and the Legendary Mirror Bundle.)
