You'd be surprised. Even with all that I've still seen DDs parse at sub 50% accuracy on things like Rex, a lot of people still have the abyssea mindset where they think they're auto-capped accuracy all the time.

Last time we did Rex only the relic holders were above 90%, and they had +35 accuracy on their weapons. 1-handed jobs and MNKs had to use pizza/sushi to even get a respectable hit rate on him to land triggers.
