I was playing a FFA game on ICO, and apparently this map was real small (Centrifuge I think?)...since one player was vasari and the other advent, I figured it was likely I'd get rushed by a Halcyon
or a Skirantra
...I was wrong, I got rushed by two Skirantras on my third planet, and all I had was a Sova (first time I've ever played MP as TEC and first time ever...EVER...I built a Sova first) and some LRMs...as you can imagine, 2 Skirantras + about 6 assailants = Doom for Sova...so I had the thing flee the gravity well (left with like 500 HP) and decided, for the hell of it, to build a Dunov (personal favorite of mine)...came back in with a Dunov, and two shots of magnetize wiped out about every single one of those damn bombers...when that Dunov hit lvl 2, I hit the Skirantras with an EMP and then high-tailed it out of there...sent in all my LRMs, and wiped out the flagship...came back later and took out the 2nd Skirantra, but of of course the guy had rebuilt the first one, so now it was 2 Skirantras with 4 repair bays...this time, however, I had a sova and 2 dunovs, and magnetize dropped all those pesky bombers while EMP made sure repair aura was never used more than once...took back the planet and destroyed 2 of 3 enemy Skirantras...
Granted, this was a pretty small map (a HW, one Ice/Volcanic, and about 2-3 asteroids per player), but nevertheless, I was very impressed by the dunov's ability to stand up to a Skirantra...I wish I had built a Dunov first instead of a Sova, wouldn't have ever even lost that planet and wouldn't have needed a 3rd capital ship...
The only other thing I've found even remotely useful against a skirantra is a radiance (detonate anti-matter)...jam weapons, flak burst, and telekinetic push just down seem to be able to keep those bombers at bay...just wondering what you all do on close range maps to counter a 2 Skirantra rush....
