Repair weapons are rarely used anyway, since it's so easy to dock and repair. So why not make 'em small-slot?

And instead of a gun, make it a small port repair beam! It takes ammo still, but at a rate of .x / second (ie .2/sec). Have the max ammo go up to a very large number like 100-200, but keep the cost similar to the current ammo resupply. Each fire would still take 1 ammo min still, so you can't exploit small baby heals.

That would make being a healer during a nasty dogfight a much more viable task. Typically when I try to heal during dogfights I will get more damage done to me than being able to heal my target.

Beam would be excelet :)

But of course there must be a range of 100m ish

Hmmm… already been suggested by me many times. STILL A GREAT IDEA!!

repair beam is good...

I'd also be a big fan of a repair l-mine
