I don't really see a rework till 5.0 either, but it's what the job needs at this point. The whole blood gauge, what you spend it on and how you gain it, is a dull uninspired mechanic. It feels tacked on just for the sake of giving the job a neat looking graphic like the rest of them. Dark Arts, a previously interesting idea for a job mechanic has been reduced to little more then having to hit 2 keys to do a GCD attack instead of one. The job's actions list is littered with poorly designed, underwhelming abilities. Tweaking numbers may make the job more competitive with the other tanks, but it's not going to make it's flawed mechanics/abilities fun to use.
