Yeah, that ability would be quite vastly overpowered (I hate using that word) compared to any other present ability. It would have to have a reasonably long duration to be useful (because let's face it, docking bombers for 5 seconds isn't going to do much), but that same reasonably long duration would shut the defender down too much.

If you want it to have a better anti-fighter ability, a more reasonable approach might be something like:

Advanced targeting - The advanced electronics systems on the Dunov can be modified to allow its array of autocannons to track fighters with moderate success. The increased power consumption prevents this ability from being active for too long.

Effect: Autocannons fire on fighters/bombers with a 50% miss chance for ~15 seconds. Another method could be without a set duration, but make it drain antimatter at a fast rate in addition to the antimatted activation cost. That way the higher the level/more antimatter, the longer it can fire on fighters.

As far as anti fighter abilities go, my dream is still to see the Kol's flak ability to resemble Battlestar Galactica's (the new series). Just can't go wrong with that

Wouldn't know, never get a Dunov high enough to get the ability Shield restore and the drain ones always get priority..

You may be right, if so, I think it should be changed. Your fighters should be immune from this effect, especially if you use autocast. Knowing you have this in your arsenal, you would equip your fighters appropriately. Like passing out gas masks to your troops if you plan on using gas on the battle field.

Could be nice, if you can time it right, you can sling all your bombers / fighters to the enemy at an increased speed... Instant kamikaze attack

The Sova's insta-build ability does work, I don't think magnetize targets your own fighters, and magnetize also prevents the target from using abilities.

But it still builds fighters faster than 1/s, and in my opinion, that is working.

fighters and flak can miss against strikecraft type targets. Also, for modding purposes, it is easy to modify accuracy ratings.

I thought someone confirmed it did have effect on friendlies?

And your right, enough thought can come up with psuedo-science to explain any wanted game mechanic
