I've been treating this as a "little known secret", but I guess it's time to let it out.
The Sera T2 PD actually does more damage than the UnitDB would have you believe. A few times, i tried to tank it with my ACU, assuming it was as weak as a Cyb T2, only to panic when I see my ACU's HP dropping fast. It is due to it doing 50% more damage than expected.
UnitDB parse:
Ultrachromatic Beam Generator (Direct Fire, Normal): 110 dps, range: 0 - 50, area damage radius: 0
beam: 2 times 220 damage every 0.4 seconds = 440 damage total
fire cycle: 1 beam every 4 seconds, 440 damage total
turret pitch: 0° ±30° (44°/s), turret yaw: 0° ±180° (60°/s)
Actual:
Ultrachromatic Beam Generator (Direct Fire, Normal): 165 dps, range: 0 - 50, area damage radius: 0
beam: 3 times 220 damage every 0.4 seconds = 660 damage total
fire cycle: 1 beam every 4 seconds, 660 damage total
Balanced? I'm fine with it.
I do think the Cybran T2 PD needs some love. IMO, should reduce its cost, instead of increasing DPS, as I think Cybran tend to prefer numbers.
