Its a difference. How that effects the balance of power... We're still working out

But, just to give an example, the Vulkoras (Kol analog)
really wants to be int he thick of things -- run it right into the middle of the enemy fleet, and let it rip. One ability increases shield regen and weapons fire, while it also has a passive ability that reduces the weapons fire of enemy ships it hits.
Deadly combo, especially when you can have all your weapons spitting at different enemy frigates
Indeed the(Kol analog) has it's place on the front lines. It also comes with a fighter or a bomber which is nice. I can't say the (Marza analog) has any battle tipping abilities but the firepower is nice.
That brings some questions I have been wanting to ask...
Can frigs/cruisers/caps attack bombers/fighters?
Can bombers attack other bombers?
Can bombers attack fighters?
Can figters attack frigs/cruisers/caps?
Is the only counter to bombers, fighters and beam weapons?
