Oh, but I should probably mention that the axe is the weapon that causes vulnerability. I think the axe would be a good choice for the build if that's what you meant. Hmm, was thinking dagger for the offhand but I just realized that since minions will take your conditions it might be better to use a scepter offhand.
Maybe with a staff as the secondary weapon, so you can pop into death shroud practically whenever you want. Also, putrid mark + fetid consumption could be interesting... minions do count as allies right? If that's the case, then you could pop putrid mark after a decent amount of conditions are given to your minions, swap to axe/scepter and use feast of corruption for a nice spike. If you have time (ie, the enemies don't walk over the mark immediately) you could apply vulnerable and bleed/cripple right beforehand.
Yes, definitely drooling.
Please don't nerf it Anet, it probably isn't overpowered.
