No DRK changes?

[ADVSS]

I main both GNB and DRK. Again we use the O S...t button to cheese mechanics or if healers slow on the gun in big pulls. If a healer such as whm cant bother to bene you for you know cheeseing a mechanic why play whm lol.

The argument made about this was that sure bene works fine, but that requires a whm. Theres 2 other healers though, in a way this also fits the tank invuln issue, not all are the same, its a bit harder for the other 2 healers, since they cannot bene. Any cooldown that "requires whm or die" its a bad cooldown, but i digress.

I said the same thing in Heavesward. Now it's just a war clone with a crappy invun. I fine dark real boring to play now.
Requiring you to save 3000mp for TBN is kind of dumb, every DRK is just gonna hover around 2000-3000mp, so its not really a skill thing really, why not just remove the MP cost and reduce its mitigation to 20% and use it every 25 seconds? And it procs a free abyssal drain, flood, or edge

well theres 2 edges to the tbn issue. You cant do anything to reduce its mp cost for the DA or its super op, giving drk no reason to pop edge or flood but instead spam tbn.
the second issue is that its there for the "resource management" and serves little to no purpose of DS having a cost to begin with, after that.
Realistically, no DRK is going to pop TBN back to back(66.6% of your mana in 15s) unless they want to go oomp, or emergency(bad decision making) so the recast could be pushed to a longer duration, and have it cost nothing.
THAT being said the boring factor would probably increase by double, but to me it wouldnt really change the core function of the job, it would however make it even blander, but at this point to me, its already bland enough, it should just -function- better. SE want to hold our hands and make every DRK good or ok, but not great? They might as well take another step and remove that penalty from TBN. Would it change my opinion of current DRK? Absolutely not. Why? Because what can DRK actually do that any other tank cannot do as well as, if not better? Thats my core gripe with the whole design. Granted its an improvement, over being benched completely, but its just a tank. A tank that tanks, and has a big sword. Big whoop.
