Considering the heat buildup and the increasing jitter as you burst fire them, I quite like that they're the way they are.I just wish I didn't have to pull the trigger for every shot. My poor hotas and hands just can't do it fast enough to get their full potential. Would love to have a multicanon like version or something in between like a burst or similar. I personally hate button mashing in any game, this is button mashing at its worst.
I run shock cannons alongside some beams on most of my civilian ships now. That combination does short work of any NPC interdicing me, which is good, since my civilian ships lack the shielding and armor for prolonged engagements. They have enough ammo to last through the usual 4 mission generated opponents without problem, which is all I need from them.
