Attually, I thought the vorlons were pretty good. well until I realised they realy don't any tricks up thier sleeve. oh and you cant concentrate firepower.
Seriously they have nothing even remotely interesting to them, balance aside they just don't DO anything execept: Close and lose, hyperpace, and still lose
to put it in perspective, average damage is no better than any other fleet, armour is decidedly worse and even with reactive armour they just keel over. In the fluff they supposedly just run around blasting with ignoring lesser races firepower.
I simply dont think the damage rules are right for them.
as for the weapons, well thier a little hit and miss, but a vorlon heavy crusier has a total of 10 attack dice, with no posiblitity of re-rolls
a warlock has more firepower in every case, and range as well, is faster, tougher (armor 6 and 70 vs 100 at 5, even with reactive armour its still a dam sight softer) it may not have as many triple and precise weapons but
I know which one I could rely on.
At least shadow ships have speed.
for reference, vorlons soak damage vs normal ship badly example
A random 6 dice super ap attack will deal a armour 6 ship an average of around 3 damage, a vorlon ship (armour 5) will take 7 damage, most hull 6 normal ships have around 70 hits, where as a vorlon ship has 100.
thats a high price to pay for crit effect immunity. typically a vorlon ship taking a crit takes around 9-10 damage, a normal ship can take anything from a crew to big dice rolls.
Basically vorlons (and even worse shadows) consistantly take high amounts of damage, and they simply dont have enough hits to soak it.
anyway, sorry rant over
