DRG Jump

[Eravel]

It's probably just that jump itself really doesn't add much in the way of damage, (I *think* it's a 2-5% overall increase when all jumps are kept on CD, but keeping them on CD all the time would probably be inefficient in the long run) and in fights like Titan ex it can very easily get you killed if not timed right. The risks of using it in those kind of fights outweigh the benefit of a tiny amount of extra damage, unless you're very comfortable with the bosses rotation and can easily tell when it's 'safe' to jump. Just my opinion anyway.
