Come on. Razors and pulses require more skill from a pilot then simple guns. Besides Three better gunboats can easily destroy a Cruiser or even a Dread if they know how. I don't see the problem here Gunboats are anti fighter and bomber ships but they can be also used as anti cap. I consider them like Wasps. One wasp can't do much damage to anything bigger then another wasp but two or three or even more wasps can make some serious damage. And honestly on this server there are like 5 people who can fly cruisers and battleship like they should be flown and those people rarely die because they are smart. So only thing you can do is to learn how to fly them or change to fighters, they are fun.
