Even though I play the Dilgar, I wonder just how much it hurts us. Let's do some math to find out... (note in the notation below, the number to the left of the colon is damage scored, the number to the right is the crew damage)
12 dice of pulsar hits vs. 12 dice of pulse hits:
Old School:
Pulse, 2 bounce(1's), 10:10, 2 crits (average is for 1.53:2.08) is 13:14.
Pulsar, 2 bounce, 8:8, 4:4 from two MoD hits, 2 crits (3.06:4.16) -> 18:20.3.
The old pulsar

ulse ratio is 1.38:1.45.
New School, Versus Redundancy 1:
Pulse, 2 bounce, 10:10, 2 crits, 1 gets through for 1.53:2.08 is 11.5:12.
Pulsar, 2 bounce, 8:8, 4:4 by 2 MoD hits, 1 crit (3.06:4.16) -> 15:16.3.
New ratio is 1.36:1.36. The downgrade is a 1.5% relative downgrade in damage caused, and a 6.2% relative downgrade in crew damage caused.
Suprising! Not as much of a downgrade in this test as I expected. The firepower ratios still feel tolerable. The crew drop is a tiny bit alarming, but probably fudgable, as long as the damage ratio is good. Let's keep trying this out where the rubber really hits the road --- Bolters!
12 dice of bolter hits vs. 12 dice of railgun hits:
Old School:
Rail, 2 throw 1's (2:0), 20:20, 2 DD crits for 6.12:8.32 is 28.12:28.32.
Bolters, 2 throw 1's (2:0), 16:16, 2 MoD hits 6:6, 2 crits is 9.18:12.48 = 33.18:34.48.
The old Bolter:Rail ratios are 1.18:1.22. How much does the Redundancy costs bolters, then?
New School vs. Redundancy 1:
Rail, 2 throw 1's (2:0), 20:20, 1 DD crit for 3.06:4.16 is 25.06:24.16.
Bolters, 2 throw 1's (2:0), 16:16, 2 MoD 6:6, 1 crit for 4.59:6.18 = 28.6:28.18.
New Bolter Rail ratios: 1.14:1.16.
Relative loss in firepower: Damage is down 3.4%, Crew is down 4.9%. These are, indeed, real firepower drops. Tolerable? Probably. I would wish for better, but I doubt I'm going to get it. Given Bolters will be the primary weapon of choice against the ships that will have high Redundancy and this test was only against Redundancy 1, it's a bit alarming. I don't mind the firepower drop as long as the drop is even across the entire galaxy. That does suit maneouver fleets perhaps a little too well -- in particular, the WS -- but after the downgrades it's already recieved, this won't make me cry a river.
In the end, it's likely the precise users that end up worst, Vorlons, Shadows, EA Missile, Minbari. Perhaps Abbai (combat lasers) and some Vree (Xixx) as well. ISA not so much as, while they generate criticals with the I-Neutron Lasers, the next set of Pulsars aren't precise, and those criticals are the best way to overwhelm adaptive; they'd rather make their pass, get behind the enemy, and then get to work. The Drakh not so much either, as their GEG weakness against criticals can be ignored ... well, once or twice. And Motherships and Carriers hate No Special Actions when they try to jump out after launching their Raiders...
I still think the Adira could be a huge problem with this, though! Hull 6, Interceptors ... probably lots, GEG 3, Redundancy 3 or more? EEEWWW!
