The Evacuater I believe has a nanite attack that lowers your armor and wreaks your hull. Those ships would easily die to the nanite attack coupled with the other ships.

5 skirmisher >> 4 cobalds
evasc has the nanite ability which makes it superior to most other caps in 1v1 at low level
turrets could not have been in range - or just not strong enough to overcome the huge advance the vasari fleet initially had

getting repair bays up is probably the best idea to deal with that. they are usually better then turrets

Only thing I can think off is that you were targeting his cap , and he was targeting your frigs.

He kills your frigs , gets a nano-upgrade , then overwhelmes your cap.

Unit control

...sounds better then micro

Isn't the nanite attack a level 6 ability? Ahriman said it was a level 1 Evacuator.

if you posted a replay of the thing we would be better able to help you.

Just a disclaimer: I would run an Evacuator with bombers up against pretty much anything.

This post is similar in spirit to a post made by Drathkar in which he had trouble with a game where two Sovas were beaten by one Progenitor.

What we are seeing is that micro as a huge part to play (i.e. were either of you focus firing? Were you focused on his cap or his skirmishers? Did you micro your gauss cannons too or did you just let them fire free? and so on...)

Another large part of it is that colony capships have powerful support abilities, in this case a debuff which was designed specifically to rock Kols. Still, it's hard to blaim class differences alone...alot of it comes down to level of play.

Peace
