I would love it if ships in conquest mode gained veterancy during their fights that allows them to fire more accurate/reload faster etc.
It would be great to have your cruiser's battle hardened crew improve and after some time fight more efficiently than their rookie comrades.
hmmm, interesting concept!
Let's say it all together now: that sounds like a good idea for a future expansion. :D
Ok I'll move it.
That is to say, I think it's an excellent idea, and I want to do it. :) It may just have to wait for a while.
