Well there is the A-61 Mantis gunship, a fairly generic one available galaxy wide and the one shown in all the Mass Effect Games. There are no other known classes, so really all I would ask is to specify which races design principles they follow. Hell, they could even be Volus gunships - it is a little known fact that the Volus airforce is a rather scary and effective force, and I imagine they'd have some unique designs. But I digress. I just wanted to let you know that your gunships would not be the ones you see all the time in the games. The other option is to use Fighters, as they are FTL capable, if you'd prefer not to have 'generic gunship design.'
This really is me nitpicking though so don't worry yourself over it.

Everyone seems to be making that mistake these days, its all good.

That is a wonderful Turian name.

And yeah I was just making sure on that count. My goal is for fairly minimal canon character inclusion, and what you intend seems fine to me with that clarification. No changes needed on it.

Your sheet is quite good, you know when the only issues I find are so simple that you've done it all right :D
