Name the canon Trek location which you would want to have added to STO the most!
This is not necessarily about functionality or which kinda location(s) STO would need the most from a gameplay point of view, but simply about which artwork/backdrop could make the most fascinating addition to the game.
My wish: Starbase 11. I love this original sci-fi artwork! (and I know Zero does, too ) Although the game already has enough social hubs, useful and useless, this would be an amazing location to be added to the game, not just for the foundry!
In terms of canonical locations, it'd be nice to see the area between Defari and Romulan space opened up, with Tellar, Ferenginar and Tzenketh. The problem is that's mostly Federation space. The problem with canon is that it's Federation-centric, which is troublesome when you have a non-Federation faction. STO should draw from soft canon licensed works and open up more areas in Klingon space, or bordering it, as well.
In terms of fantasy pipe dreams, I'd love to have the Maelstrom and the Kessok from Bridge Commander.
