Looking for easy to pick up and sturdy DPS class

[Shurrikhan]

Black mage says hello.

You... have the best self-sustain skill of any DPS, unless you're somehow going to discount shielding. Manaward's 30% of HP, and as a long-lasting shield of all things, rather than about 15% HP per the same 120 seconds, says hello.

Or is being able to pre-pop that self-sustain, and to use it survive attacks no other DPS can, a weakness?
