Okay, first let me say that I do really enjoy what you've written up here. Its good to see someone working on helping to flesh out the more lore starved race. However, there is something that I find myself in disagreement with. Namely that the feral tendecies of the Gilnean Worgen have been removed. From everything I've found on the subject this has not been the case.
Most people seem to be getting the idea from the end of the Tal'doren questline. However the final quest doesnt actually say this.
Well of Balance:
Talran of the Wild says: Let the Scythe unbind that which was not meant to be bound! Let the soul master the beast, lest the beast master the soul!
Vassandra Stormclaw says: Just as Dral'nir soothes the cursed druids who gave into the beast and abandoned balance, let Tal'doren soothe <name>.
Lyros Swiftwind says: Just as Goldrinn's spirit once blessed our druids, let <name> be blessed with the wisdom of his race and the ferocity of the wolf god.

None of these say that the feral nature of the Worgen has been removed. Only that the sentient mind, human in this case, has been 'freed' from the feral allowing it to extert some level of control. Not removing the feral and having the normal mind fill in that gap as many seem to believe. As can be seen in the Duskwood questline with one Tobias Mistmantle.
Stalvan appears in the manor.
Stalvan Mistmantle says: My ring... Who holds my family ring... Tilloa, is that you?
Tobias walks into the manor and confronts Stalvan.
Tobias Mistmantle says: Brother!
Stalvan Mistmantle says: Tobias...
Tobias Mistmantle says: Tell me it's not true, brother. Tell me you didn't die a murderer!
Stalvan laughs.
Stalvan Mistmantle says: It's all true, brother. Every word. You doubted it?
Tobias Mistmantle says: But why?! How could you?
Stalvan Mistmantle says: You know why!
Stalvan Mistmantle says: Surely you've felt anger. Anger so foul and vicious that it makes you want to tear someone to shreds...
Stalvan Mistmantle says: Aren't you feeling it right now?
Tobias morphs into worgen form.
Tobias Mistmantle yells: No... NO! STOP IT!
Tobias and Stalvan begin to battle. Help Tobias kill Stalvan.
Stalvan Mistmantle says: You see, brother... we're not so different...
Tobias Mistmantle says: No...
Tobias rushes out of the manor, back to Darkshire.

Tobias looses control, his anger overwhelms him and the feral mindset jumps back in control. It wasn't removed, either by the Gilnean alchemy or the Druids magics. Indeed the druid magic did exactly what druid's are supposed to do, restore the balance. You cant take the feral nature out of a Worgen anymore then you could sunder a Night Elf's connection to nature or an Orc's bloodlust or a Gnome's need to tinker and fiddle with things etc... Its part of what they are at a fundamental level, no amount of magic spells will ever change that.
