Martial Gun is phenominal for the excessively powerful and innacurate Slug Shot. The reason it's not used by RNGs (from what I can see) is that between Acc Bonus IV and A- skills (as well as weapon/armor discrepancies), that Raac isn't needed, so they get better milage with a pure damage gun like Hellfire +1. For COR the Raac is needed, so it's a perfect match. Also as far as RNGs not using it, obviously the value of it is all in WS, yet RNG is ranged TPing where we're meleeing for TP.
Martial is only strong for jobs with terrible Acc. When it came out, RNG didn't need the RACC at the level this gun becomes available and no other job had Slugshot. So these guns rotted in the AH until COR was released and with our ****** B skill and lack of RACC traits, we were obliged to use this gun. But it isn't powerful. Hellfire is powerful. Culverin is powerful. This gun is accurate and that's it.
But since it was there already and SE knew it was there, why couldn't they have designed the hexaguns or the COR job to not require the martial gun to function properly.
The QD formulation should never have been based on gun + bullet damage. COR should have been given some base ACC traits. Our endgame bullet shouldn't cost 20k gil a stack.
If I were to design COR from the ground up, we would only be allowed the hexagun line. It would add AGI which would formulate into the QD damage equation as well as accuracy. We would get two ACC traits and we would have endgame bullets that capped out at 10k a stack (but could be crafted for 5k a stack).
We'd get Snapshot natively. WE'd have our own unique hexagun WS's and no slugshot. But something decently powerful to keep up with the dancing edge dancers and thieves out there (i.e 1k with decent gear).
No Joyeuse or M KRis COR's. We'd be ranged attackers with a decent gun and bullets but nothing that would eclipse RNG. We could do decent DoT, average WS's, good QD's. We'd still be expensive and not everyone would play this job, but we'd at least use our hexaguns effectively.
Or they could just give us hexaguns with MAB +20 and I'd use them pretty frequently in many endgame events.
