Wandering Plague (UH DK Talent) needs work

I have been a Unholy DPS for a while now and have alot of experience seeing all of the various talents of Unholy and how they stack up on DPS. It is well known that we tend to fall behind blood abit in single target and I am cool with that because we really do make up that ground in multitarget fights (which is balanced in turn via the tendency for 90% of meaningful DPS fights to be single target).

Been 80 for a while now and have been building up a decent set of gear with AP closing on 3200, crit over 25%, and my hit way over the melee cap and close to the spell cap. All this time playing as a Unholy DPS I have been logging all the various DPS I do and keeping track of where the damage comes from and wandering plague always ends up way near the bottom of the list doing about 2-3% damage over the course of a heroic, this is bumped up from the group pulls because breakdowns on bosses has WP at less then 2% normally.

So I figured "hey, it is simply not great on those small group pulls and sucks on bosses, fairly useless talent for the most part but at least it would shine in true AOE". Enter today and a Culling of Strat Heroic I go into. I decide to really push the DPS up via WP and thus every single fight starts off landing dots on a elite and then spreading them to the mass of mobs we have trained to an area of the instance. There were times we had 6 elites and dozens of non-elite mobs, the numbers from UB and D&D which I dropped after were nuts, but at the end of the instance I took a look at the overall damage that Wandering Plague did...

5.4% of my personal total DPS came from Wandering Plague. And when thinking about this keep in mind, this was on full out training huge amounts of mobs AOE bliss. Wandering plague is never going to get a better chance to DPS then in fights like this. Auto attacks on these fights targeted on a single mob at a time amounted to over 4 times as much DPS as Wandering Plague managed to do to the whole group of mobs all about.

My Gargoyle I popped on Malygos did over 1/3rd of the amount of damage on that single fight then Wandering Plague did in the entire freaking instance.

This is with me making sure that frost fever and blood plague are spread asap to maximize the WP DPS.

And this instance is not a fluke or bad luck, it is the best DPS I have ever seen by far out of WP, a seriously underpowered talent atm given the depth it requires in the Unholy tree and the 3 points you spend in it.

Perhaps the problem lies in the fix that supposedly exists in 3.0.8, some reset. I hope maybe the talent is somehow just broke atm, because if the supposed fix thing is not the main cause of this pitiful DPS from this talent the thing needs some serious looking at. Supposedly in Beta the talent was insanely good and overpowered, well now it seems to be on the complete other side of that coin and is usually competing with Blood Caked Strikes or the 3 points I have in Necrosis at the bottom of my DPS breakdown.

I could care less about BCB and Nec, I took them as filler and they are clearly aimed at Duel Wielding although they don't exist in the frost tree where the main DW talent is and fubar our mid tree talents forcing us to take then to simply get to the meat of the tree although if you use a 2 hander they flat out suck. I do care about wandering Plague though, this is a deep Unholy tree talent that really defines the type of playstyle and damage the tree is based upon and atm it is just weak, really really weak.
