What happened is that atm community frequently use prebuff COR then just buff and drop. My last melee woc (when I was on tank) we even used 3 prebuff COR for 6 rolls.
If SE gives COR 3 rolls it'd just encourage community to continue with COR prebuff and drop, it's just that now we get 3 rolls per COR instead of 2 rolls so we can settle with 2 COR mules for 6 rolls lol.
IMO it doesn't solve any of the issue, nor make the job more desirable. To make the job more desirable the best way is to make the job stronger DPS so at least it has a reason to stay in the pt after buff.
In high lv melee pt this job is pretty bad when it comes to accuracy. Not just because of B ranked skill, but also due to the lack of top tier melee weapons. Melee DPS is also pretty bad compare with melee REMA DDs. Better acc also means better TP gain in high end content to setup skill chain with real DDs etc.
This job is never designed to be a full support job like GEO and BRD anyways. It's REMA are all DD weapons, and it's armors are mostly light DD armor. By comparison GEO and BRD has support REMA and mage gears.
Regardless, even without reisen melee weapon I feel the job is still just right in terms balance. Leaden SC fits in damn well in BLM setup, and COR savage blade build is still pretty strong as melee in terms of DPS. COR's support ability + it's DPS atm still outperforms using another job for the same slot most of the time from my experience, unless the pt is setup to do MB with elements that's not dark.
