the armour value of 1 for the Darraor Light Frigate is effectively irrelevant ( if i'm reading the rules correctly) as 1 is already a bulkhead hit.
As far as I can tell. That's one comment worth making - the armour values do seem a bit on the low side.
It makes for a very different fleet, I'll agree - rather than shields (which absorb a fixed amount of burnout hits then go kablooie for the turn), armour gives you an ongoing, irreducable damage mitigation (I notice there are no armour criticals anymore!)
One thing you have to bear in mind is that they are not going to be getting more criticals than any other fleet. Rather the proportion of criticals to damage will be much higher.
Actually you do - the hits absorbed by the shields don't generate criticals, after all.
Assume a couple of volleys of 7 light lasers each on a destroyer:
"Normal" destroyer:
Volley 1 - 3.5 hits, 3.5 shields burnt out, 0.5 shields remain
Volley 2 - 3.5 hits, 0.5 shields burnt out, 3 damage
Net: 3 damage plus one critical
"Old Vuldrok" destroyer:
Volley 1 - 3.5 hits, 3 armour hits, 0.5 damage
Volley 2 - 3.5 hits, 3 armour hits, 0.5 damage
Net: 1 damage plus 1/3 of a critical and a lot of swearing from the opponent
"New Vuldrok" destroyer:
Volley 1 - 3.5 hits, 1 bulkhead, 1 damage, 1 critical
Volley 1 - 3.5 hits, 1 bulkhead, 1 damage, 1 critical
Net: 4 damage plus 2 criticals
Okay - Li Halan broadsides are a 'worst case' example, but you do end up taking more damage and more criticals. Now I like this new mechanic, I do. If 'bulkhead hit' means a ship's armour taking the punishment and no structural damage resulting, then that's
exactly what armour should be. Equally, taking more criticals is fair enough because (a) 1/6th of criticals are ignored and (b) you're not stopping the damage before it strikes the hull, like shields are.
But the armour values are a bit low. So long as 'a six or more is a critical' is unaffected, armour should probably be as high or higher than equivalent shields - you're taking less structural damage as a tradeoff for taking more criticals. Since criticals are no longer 'bang! headshot!' like they were in 1st or 2nd edition, it's not so big a deal as it might be with the equivalent, Narns or Brakiri.
