Vorlons and Shadows *seem* to be vulnerable to what we nicknamed 'crap dice' attacks - hitting them with lots and lots of dice, no matter what traits were on the weapons.
Yes, I noticed that myself when I took Abbai against Vorlons.
Scimitar,
My gut reaction is that would be a LOT of additional dice rolling, and more dice rolling = bad. I'd also say that it wouldn't help with the fundamental problem of Minbari firepower against the weaker fleets and would make the Minbari too weak against those fleets already capable of taking them on.
On the one hand I'd say lets think about toning down the Minbari and Centauri firepower while leaving everything else the same, but on the other Wolf's solution of boosting the EA and Narn might work out better. In either case, I think Stealth is the wrong target.
What would happen if we dropped every EA and Narn ship above Skirmish by one PL? If EA and Narn really are underpowered, then dropping the PL in a few test games should reveal the truth pretty quickly.
