In Overseer, the Quests that reward tradeskill supplies are missing the poison reward of "Luclinite Laced Nigriventer Venom" from the Terror of Luclin reward choices. The Torment of Velious tradeskill rewards had this item as a reward as do previous expansion rewards.
I knew there was something odd about the ToL rewards, but couldn't quite put my finger on it. I typically use OS rewards for making stat food, so just end up destroying the poison stuff. I like not having to do that with the ToL rewards. But, you're absolutely correct...the rewards need to be consistent.
And Luclinite Laced Gormar Venom, and other poison items should also be on overseer. And not sure if these drop from any NoS mobs, but that would be nice too.
Now that I think about it, I think maybe the reason they didn't add it to Overseer rewards is because the same drops are in NoS and there are no new poison recipes with NoS. I think they didn't want it to be THAT easy to make the only current poison items.
