I generally like all the ideas shared here. I like many of you am a fan of the Galaxy Class and to see it be treated in such a negative light is just sad. Due to her many problems I had to switch to another ship.
Although, I like the ideas here I was thinking why not reward true Galaxy Class fans. The Devs can still make a ton of profits if they plan it right. I'm not suggesting anything new or that has not been already said.
Overall I think this would be fair because so many true Galaxy Class fans already have this or would really pay to get this.
Antimatter spread console + saucer separation console + heavy tachyon beam console (the devs would create this)
No matter what happens the set bonus needs a turn rate buff because of her poor inertia
