Considering the revisions they're making on Samurai, and Warrior why not?
Everyone is getting significant damage boosts, yet you're happy being sub par, as long as you can live a bit longer?
They want the community to speak out, and say what they want. So far, the community wants pretty Wyvern colors, and Stout Servant, and bigger Wyverns to better show off the pretty colors.
It's never just 10%, 5%, include the merits that they can obtain, the gear that can be worn, and these jobs are looking at give or take 25-40% DA/TA rate. You want to consider Quad Atk as overly powerful, it's something I threw out there.
Personally, I'd like an Occasionally Jump's Mob type of DA, our own personal little unique trait.
You could list forever the things SAM, and WAR has. Traits, abilities, gears. They're catered to jobs, simple.
As far as Dancer goes, it's not a set in stone thing just yet. Because of Saber Dance is why I think it'll probably just be some type of boost to triple attack, maybe a samba of sorts. Since it would make Sabre Dance worthless since everyone would just spam the triple attack proc stuff. However, we'll see.
