I would propose that the trash drop rate in ValorB would have to be increased by at least 4x (to compensate for the four lower Thaz wings) to make up for the disparity in the number of mobs available to kill between the two zones. Right now it's like we only have Lower Earth to kill over and over and over again to complete the quest.

These replace the Eldritch Steel from Upper Earth, which was a tiny wing with only sixteen mobs. Given that you need quadruple the items, a droprate increase to match will be seen. Other posters claiming that Upper Earth had a quicker respawn or easier mobs compared to valorb are not accurate. The drop rate in valorb was probably too low, and Jumbers has already posted to say that this will be addressed. The intention was, and is, for the Valorium Ingots to be the same amount of effort to obtain as the Eldritch Steel.
Look for this to be changed in the next patch and hold further assumptions and complaints on the droprate until then. You got something you wanted, so cheer up!
I still think only one ingot should be necessary. This is what we know [...]To be honest, this is a SoD Admin team made traffic jam. I really appreciate the work Dev-Jumbers and GM-Olive put it to make it possible to do this again. However, the team that took out Thaz but then didn't update the vah quest really have caused a mess. There needs to be changes made to get the 1.5 years of knights ready to do this quest through it with minimal affect to the guilds ready to move through these tiers. Having 8-10 over tier knights perma farming these zones really isn't the answer.

As to this point, and the general tone of many posts in this thread: While I understand your frustration as a player, please consider the challenges to the staff. If this was a new quest, people would be more patient with issues like this. As an existing quest, there is outrage at oversights, and a sense of entitlement to content being updated quickly. Please remember that the people who designed both old Thaz and the Vah are gone. It can be difficult to update and maintain the content of others while still adding your own. We have fixed a broken quest, and been open to player suggestions about a drop rate increase. I am not really sure what more a reasonable person could expect. It is easier to look back and claim that in hindsight the quest should have been changed right away. But game development is a process in which things sometimes become broken for a time. All we can do is move forward from here.
When Thaz was redesigned as a higher tier zone with all new content we were faced with a choice. Either stick with the original progression of the quest and add drops to new zones, or force people to do higher tier content for their drops. A temporary backfarm for some characters was deemed a better solution than messing with the whole progression of the quest and adding the drops to new Thaz. Let us wait and see how the improved drop rate shakes out before we consider adding the drop to every raid mob out there. Plus, the server could always use more PUGs if you are rotting the gear! Valorb is a pretty fun zone!
Lastly, I appreciate the thanks to myself personally but I cannot take that credit. The amount of effort I put into this fix pales in comparison what the Admins do for the server on a daily basis. It may not count for much, but my opinion of Woldaff, Slaar and Jumbers has gone up immensely since I joined staff. The hours they put into this game is above and beyond what I would expect of volunteers. Maybe this all sounds like a big list of excuses and all you care about is that the quest was broken for so long. If that is the case, then all I can say is try to let go of the bad feelings over the 'mess' and the 'cleanup' will go much better for all of us.
edit: In case it was lost in all the words I posted: this takes a patch to fix. We have changed the drop rate, but please wait for a patch to add more feedback on drop rates. We may reopen the thread then.
