I'm more concerned over how support skills will work. At lower levels, those skills can be crucial to have, and as we all know jobs are highly restricted in what they can use compared to base classes. For example, I deteste tanking on WAR at anything lower than level 30 (no HP+, no heal+, no defense) , but as a MRD I don't mind as much since I have bonus skills to help out (Second Wind, Convalescence, Flash, Provoke..).

Since DRK is going to be a tank *shudder* hopefully it will get a few more cross-class skills than your average job.
