I still sub warrior over dragoon on Ninja. Feels right still.
Revisiting this, as it's the only thing in Buukki's post that I didn't agree with...
What's the value of /WAR these days? I'm almost always on /DRG now, especially for segments.
DA+12% and Berserk/Defender/Provoke just don't stack up to /DRG's WSD boost (on all hits of a WS), especially once you hit /DRG55 for the bump up to 10%. Jumps (mostly for occasional enmity management) and Conserve TP are a bonus. I find /WAR doesn't hold up offensively even when riding Berserk as much as possible, and that comes with risk too if you ever get shadows wiped and take hits with massively decreased defense. DPS gap grows even more when you're not using Berserk.
Really the only times I /WAR any more are for Abyssea procs, or rare situations where I might want to focus more on tanking and Provoke and Defender have some value. Voke shouldn't even be something you use to pull a random mob, just get in the habit of pulling with Hojo or Kurayami instead, and get the benefit of maybe sticking an enfeeble too.
