Cor is about buffing. Why nerf a job who is based in tp so that you can please a group of cors who have waaaay more buffs to pick from. Thank god they didn't nerf the regain roll eh?
The whole idea of progressing to level 99 for COR would presumably mean getting new rolls that add further power to the job. If we are just going to be using old 75 level rolls, why bother advancing the job at all? Tactician's/Miser's are the only two of the whole batch of 76-99 rolls that gets any use from most COR's. With the nerf, it will only be Tactician's. That's one roll in 700k gil of new rolls. Did BRD not get upgraded songs across all their lines? Are they using only level 75 songs these days?

COR is a buffing job that had found a niche in VW due to a powerful roll. That's being nerfed to a level where the roll becomes totally useless. I've put up with useless rolls on COR, but never had one that was useful become useless with a change in formula. We're not talking a minor tweak to balance it. We are talking making it totally useless.

All COR's are asking is to turn Save TP into a capped trait. 50TP returned makes it still powerful and doesn't make it totally useless. And it nerfs it to a level where all here pretty much agree its reasonable as far as balance.
