Hey, would you mind elaborate? In what situation do frag cannon give you an edge?
Since they have a total of 11 bursts, they are definitely not good for long session of PvE kills.
Since they are ineffective against shield or at long range, they generally will not do for PvP where everybody relies on shield cell banks and run away as soon as the shield drops.
Now, I agree that one bust of frag at close range is equivalent of 4 cannon shots against the hull, and since it spreads, easier to damage modules.
=> So only good for a few / unique PvP kill, where you blast the shield of your opponent at close range then frag him to death before it flies away? Or for PvE assassination missions?
From my side, I use an all cannons setup on a Cobra, kept at its top speed all way long at conflict zone, and have way more fun than flying a two beam Vulture. Feeling like a supersonic bomber! However I must wait to find a shieldless prey and also bring way less vouchers than I used to with my Vulture...
It could also be used on Python/FdL to keep 4 pips to shield and fly like a tank
