[DRK] Wanna know why Unleashed & Abyssal Drain are both needed?

[LordHousewife]

Because while Abyssal Drain deal slightly more damages for a slightly higher mana cost...

...Unleashed:
- Doesn't consume your Dark Arts buff (that you'll most likely use for a Carve and Spit)
- Doesn't break your combos, and this is your only GCD having this property.

I've been wondering why people never mentioned that in any of these QQ-DRK-threads so I thought you guys just didn't know.
This is extremely helpful in A2S, where DRK is -spoiler alert- (once again since A1S) the best tank.

DRK is the worst tank in A2S since almost all of their abilities that you would use while regularly AoE tanking are rendered useless. I am not sure where you're getting that but yeah you're wrong. I'd honestly much rather be a WAR or a PLD in A2S than DRK, which incidentally is why I am leveling WAR atm and why none of the top progression groups use DRK in A2S. The reason why it is used so often in A1S is due to the magical tank buster that DRK can effortlessly mitigate with DA Dark Mind + Shadowskin stacked with Delirium 100% of the time, guaranteed. You could apply the same logic to any of the other Dark Arts skills and claim that they need an equivalent in order to not consume the Dark Arts buff (which is stupid because you should plan around Abyssal Drain, knowing that it consumes Dark Arts. Both skills literally fulfill the same job and only one of them is needed. Saying that one consumes DA and the other doesn't is a flawed argument because there are 6 other Dark Arts skills that don't match that logic at all. That's like saying we should have another version of Powerslash in case I don't want to use Dark Arts on it (which believe me I don't want to, therefore I don't use it).
