Since Franklin Drake was swapped out with another officer In "Under The Cover Of Night" I think it would be cool to reintroduce him in a FE story arch. "The Devidians" doesn't count because it's assumed we already know him. (unless that's been changed, since I haven't played those missions in quite awhile.)
I would also like to see "Divide Et Imperia" redone for reasons that have already been stated enough before so I won't go into them. It's been stated somewhere that the Tholians are comming at some point, so I don't need to go on about that either.
On a side note: To get content moving a bit faster, I don't think anyone would mind if the VO were only done in cutscenes. I tend to read faster than they talk (I bet most people do) and skip past those anyway, soooo...
Just a couple ideas off the top of my head. I'm sure this stuff has already been kicked around the idea room at Cryptic, but thanks for reading anyway.
