use lots of units and fighters
Neither Fighters or Bombers work against Light Frigates. Fighters are worse than Bombers at it. Despite their name "Light Frigate", they don't actually use Light armor.
Do you think the improvement of the Illuminator in the next patch might even things up?
Frogboy's words:
- Illuminator:
-Hull points increased from 520 to 620.
-Shield points increased from 450 to 550.
-Attack type changed from CAPITALSHIP to ANTIMEDIUM.
-Front bank damage increased from 33.8 to 65.
-Side banks damage decreased from 33.8 to 26.
So after the new Illuminator Vessel 1.04 arrives, you'll get:
188%
more damage from the front beam, against Cobalts.
15%
more damage from each of the side beams, against Cobalts.
22%
more shield points.
19%
more hull points.
All for the same price. The only loss is in speed, down from 800 to 500.
Until then, you've got Cleansing Brilliance + Malice as an anti-Cobalt-swarm weapon.
