To all those mentioning psionics as a base class: Savin told me a couple years back that it's something they want to add but need to progress the game more before really working it out. In other words, it'll come when it's ready.
As for requests, I'd love to see a way to repair the Fenris Assault Drone outside of being a Tech Specialist or going to the Kiro quest...mostly so I can take the repaired drone to the Kiro quest and get Fenris 2.0. Likewise, it'd be nice if Tech Specialists could use Drone Accessories as either a second drone (taking up your accessory slot) or just replacing your normal one but leaving your accessory slot open; drones are supposed to be a special Tech Specialist thing to help the class stand out, but if you want to use one other than the bog-standard one, you have to give up your accessory slot like everyone else and also lose your drone's shield bonus, effectively negating a perk. That, and it'd be nice to be able to use both of your attack dogs in tandem (Fenris-drone and Varmint tag-team for the awesome!).
Speaking of both, I'd love it if there was a random scene when boarding your ship with both the Varmint (trained) and the Fenris (repaired or upgraded only) already on board (so neither of them travelling with you whether as a drone or an inventory slot) playing together, sleeping together, etc. as a small pack. It'd be cute, and really funny to see a silicone-devouring space-dog-thing and an advanced assault-drone just being adorable together and getting along. It'd really give a sense of liveliness aboard the ship (and as far as I am aware, neither take up crew-slots on your ship, so it shouldn't interfere with the current system that much). Heck, more scenes like these in general would be kind of nice (Celise and Nova having a "morph-off", Anno and Azra comparing notes with regards to planetary effects on the development of non-native flora, Paige and Pippa discussing nerve-glides and pressure points, etc.).
...hmm, I might be feeling the urge to write something...
