Personally I think a nice fix might be to take stealth (improve its shields/hull a tad to compensate) and scout off what is currently the scout, reclasify the current scout as a 'destroyer' or hell, call it a stalker if you like, then make the 'scout' the battle level version. Give it stealth and scout and the advanced scout ability the Leshath has (its a frickin first one scout ship for crying out loud).
This would have a twofold effect:
Firstly it's never seemed 'right' to me to see the average shadow fleet made up, generally, of swarms of 'scouts', a ship that is basically an advanced recon ship that doesnt usually opperate in huge numbers. And secondly it would make the battle level version actually rather useful even if it wasnt as potent in firepower or sruviveable as 2 of the raid level versions. It's not a big change but personally I think it would be a good one.
