All set bonuses are deplorable. Period. Most mix parts of each, and no one really completes a whole one, short of people who rock a legacy set.
Which leads me to my last point. Nats non legacy set...with the +20 discipline...gets the shortest end of the stick. DHs are not viable past mp 1 or 2 without one skill. Gloom.
They took stat points out, so we will never know how the other shadow power skills would play out if stacked. Currently the only useful one [and mandatory] is gloom.
Second to that is some sort of Vault.
You can have 40 discipline, or 60. It does not matter. What happens when you run out of juice, and it regens at 1 per second. You most likely die. Or you kite an run away and wait. And wait. And wait. AAAAAAnd wait. Until your disc fills back up.
Its totally flawed. +2 disc regen may have been too much, but +1 would have been fine. +20 disc is stupid. It delays the inevitable for the DH...running out.
I notice my question in ask the devs about this problem was ignored.
Anyway. Until you figure out what you want to the set, a buff or a nerf, not both, don't post an whine about it on the forums. Worse then a fat kindergartner stealing everyone's toy.
I wanted to clarify that there are no set bonus changes coming in patch 1.0.7.
If you are curious as to what changes are currently planned for patch 1.0.7, please peruse [url="http://us.battle.net/d3/en/blog/8414570/public-test-realm-patch-107-notes-updated-131-2-1-2013"]our latest PTR patch notes[/url].
Change the set bonuses. Seriously.
Nats 2pc is obviously overpowered (I own one on my DH, not on this mule account obviously, but 7% cc is just a joke. 4.5% cc would be more appropriate).
Other set bonuses just flat-out suck. IK's 3-set bonus, Inna's 3-set bonus, Tal Rasha's 2/3/4-pc bonus, they can all use a buff.
Also, the Demon's set. It's horrible, please do something about this set.
