I have been a DRK main since 3.0 released, and there has been something bothering me about this job. Coming from WAR (which imo feels perfect right now), I have been taking note of what I think is making me feel this way.
I don't mean to start another "fix this or that class" debate, but just wish to share my thoughts about what could be done to make it feel smoother overall. A quick note, I will be comparing DRK to WAR at times, since I feel like they really hit the nail on the head with WAR.
1) Reprisal isn't reliable as MT and useless as OT. Warrior gets a straight up 10% damage debuff built into a combo, meaning they can apply it whenever they wish. Of course, I understand they shouldn't just copy paste abilities or things will feel too much the same. In this case, I would make Reprisal not require a parry proc and instead be an oGCD ability (as it currently is) with a 20 second cooldown. The reason for this, is that you can only apply it to a single enemy at a time(whereas WAR can apply it to multiple), but it keeps the benefit of being oGCD with extra damage.
2) Change Dark Dance's DA buff to give you TP back instead of evasion. A simple switch that would make a huge difference. It doesn't need to be a large amount of TP, just enough to keep you going (similar to how WAR can gain TP). In this case, it varies in the sense that you must sacrifice MP to do so.
3) Swap Delirium and Souleater's potency. The reason for this one is to make your main damage combo more useful. Instead of just constantly re-applying the INT debuff (and clipping it), you could be gaining a small amount of self healing. I'm aware that Warrior also has the issue of having a higher potency debuff combo, but this would solidify DRK as the self healing tank. If nothing else, simply swapping the potency when turning Grit on would add self healing for MT while still keeping Delirium the higher combo when OT.
Anyway, what do you guys think? These are just my thoughts of what feels off, and I fully realize that they likely won't be put into effect. Just fun thoughts of what could be done, and would love to hear if anyone else feels like PLD and DRK just don't feel like they quite match up with WAR right now. Again, not trying to whine or complain about DRK, just hoping to see PLD and DRK be buffed up a little bit to be more on par with WAR.
