I'd like to see a tellarite ship added to the game as well, just so we can see all the founders of the federation represented in the fleet. I agree it should be a cruiser, and I think the ones we saw in ENT look good and unlike anything else in the fed fleet right now is a plus. Don't really care about any gimmicks, like that it would already get crusier commands, which is nice enough for me.
If I recall, it had pretty large cannons on it, maybe make it a low-tier battlecruiser seeing as that cat's already out of the bag?
Tellarites are a very minor species. It probably won't be implemented.
Tellarites are a founding species of the Federation: Humans, Vulcans, Andorians, and Tellarites are the 4 founders.
Cryptic has said they want to get a ship from all the Founding species into the game. The Tellarite ship has been in development for some time and could be the broadsider ship design Geko is often talking about.
