DRK balance

[Xlantaa]

I consider DRK a perfect balance between mitigation and damage. But it have some advantages like more MT dps and more magical mitigation if the boss is magical type. It also have a very high OT DPS, more focused on sustain DPS than burst DPS. I main DRK since 3.0 launch. I was before a PLD/WAR, I won't be again PLD/WAR as main (Samurai tank can chage my mind...)

There are only 3 things that must be adjusted for me.

1. Living Dead need the healer know what is it and how deal with it. That's not possible always, it need chage is invulnerability effect to something easier to handle.

2. Grit should be out of global coldown like the warrior Defiance, it makes hard chage stances quick.

3. Dark Arts should have less cost. The MP drain with this is too high and you can run out of MP accidentally a lot of times.
