Hello, a BRD here. o/
While I can’t speak for others, I would take Diversion’s 90% reduction in enmity generation over Refresh’s/Tactician’s 50% aggro dump. They rarely serve to be sufficient, because I always end up crawling back up to #2 before one (or both) are off cooldown, since a BRD bursts every 80 seconds when they enter Minuet+Raging Strikes. Diversion would serve much better for these burst phases, since it will reduce your aggro generation by 90% for 30 seconds, rather than just half it. Especially since Refresh/Tacitician should be used first and foremost for resource replenishment, not for me to save my own skin. :x I’d happily trade the dumps for an enmity queller.
The difference with DRK and PLD is that there are options for the slashing debuff: WAR, NIN, and SAM. BRD/MCH have 1 option for piercing, and one option only: DRG. In addition, all other DPS jobs can apply their own resistance down debuff (slashing, piercing, blunt); BRD/MCH are the only ones who do not have that ability, and they lose out on 400~500 DPS because of it. Casters’ damage is calculated without having to rely on a “magic resistance down” debuff; they don’t have the same problems BRD/MCH do.About the second part, both dark knight and paladin depend on a slashing resistance down capable job. Casters are a whole different can of worms.
Honestly, the developers need to either give BRD/MCH piercing resistance down, or remove it from the game (and buff potencies accordingly for DRG, BRD and MCH; because DRG will die if they don’t buff its potencies). Honestly, all the resistance down debuffs need to go. Considering all DPS jobs can apply their own save two, there’s no reason to have them. There’s the “they offer synergy” argument, but the only “synergy” piercing has created is the physical meta of DRG/BRD/MCH that has been present since Creator. People love to hate on the meta, well the easiest way to break it is to remove piercing. Because that’s what’s holding together DRG/BRD/MCH.
The issue with Stoneskin’s duration is that you rarely benefited from the full 30 minutes; most Stoneskins were broken pretty quickly upon entering combat, especially on a tank where they are more useful. Stoneskin II could only be applied outside of combat, thereby limiting its effectiveness. It would have been far more effective as an AOE shield/mitigation option if WHMs could have used it during combat. But, since they couldn’t, it was essentially worthless.
I would take Benison over Stoneskin. It costs nothing to use (other than it will still eat your lilies to reduce the CD timer, but it doesn’t cost MP like Stoneskin did), is an oGCD I can weave between GCDs, and it mitigates more (15% of a target’s max HP as opposed to Stoneskin’s 10%).
