Disclaimer: I accept that my idea will be mock and may not inspire anybody but damn it I'm putting it out there. There should be more content given the is time to shoe horn in some. please also note that these ideas are also basic and may be edited in the future for an in-depth idea how each class will work in game.
We have three classes out there, but in the end would be pretty dull if we want to play PC class. So why not add more classes I may not have a good one but here's some ideas. Trader (Aka the Easy class)
Ok this class needs some explanation if your running low on funds or need to lower some of the prices, the trader class will be just for you. we all now that traders are gifted with the silver tongue so this class should be able to convince some traders to lower they're prices...well some of them. many Traders can defend themselves so the PC can do the same to an extent.
Cybermancer
like the name suggest the Cybermancer classes will allow you to use nanobots of your own creation to hack other robots or make some of your own. the Cybermancer however is a glass-canon and should be use with caution you can easily get a game over if your not careful.
Outlaw
I'm not sorry but They really let themselves be open for this punch of anime reference. The outlaw is a dual gunslinger class that can mix melee weapons with range weaponry the outlaw can also out maneuver some opponents but have a suspicious eye cast over them. Outlaws are not trusted in some areas but can be made right at home with others.
Slaver
yes I'm putting this out there I want to be a slaver in the game or have some option to be good buddies with a slaver faction if they are going to do that in the near future or so then i will gladly delete this Class from the idea list. as the name may incline you as a slaver can capture enemy's that are not consider necessary to the plot of the game and train them to the will of any slave market out there in space. you can also seduce some NPCs that what your doing is right and can easily get away with it you can also keep some slaves as pets.
So here are my Basic ideas of some classes that may or may not influence people to be added it's up to you or me i care not either way. I just wanted to get this out there. If you have some ideas too or maybe what to add some input on the classes I posted above please leave a reply would you kindly but let it be positive or negative like I said I care not which.
