I see no issues with the current system. The beam is small because if you have ahuge beam comming out of a single block then it can only hit a single block, if you want bigger, you need a latticed array.
Imma just leave this here.
While that picture is cool and your design is definitely creative, it doesn't solve the problem here. The problem is that the damage beam's beam effect does not scale in size to its weapon array. We should not be forced to make these "lattice arrays" just to have a logical-sized damage beam for a large weapon. Again, we don't want unofficial halfway-there shortcuts, we want official and authentic solutions to this issue.
I dare say you have missed the point of this thread.

Then how do you explain why cannon shells scale in size to their weapon array? Should they have to be spammed out of multiple small outlets to make sense to you?
Secondly you have huge missiles coming out of a single block but they don't damage a single block now do they?
FYI beams can do wider damage too with explosive effect.
Regardless of whether or not the beam is small, I doubt the majority of people think the idea of massive yet tiny laser pointer deathrays is an appealing appearance for their capital ship weaponry. It is senseless for a large weapon to emit a tiny little beam, not to mention boringly redundant. Large weapons should not only be powerful but their strength and size should warrant a grand display of beam fx.
