This is how the old sets looked like:
Ebon Armory
Hircine's Veneer
Worm's Raiment
If you want to look how the new styles look like in Thieves Guild open the containers on PTS at your own risk. I did that and was extremely disappointed with what I found...
With the Thieves Guild DLC the old sets that provide buff to 12 person groups have been reintroduced. The Ebon, Hircine's and Worm sets are scaled up to Veteran 16 and will be available from the new trial. That's brilliant news and thanks to Zenimax for brining these great sets back up to date.
However, the new sets come in the frankly horrible design that is identical to other sets that will drop from Maw of Lorkhaj. My question to Zenimax is why would these iconic sets have to change their appearance at all? Please revert to the same original design which is unique and so pleasing to the eye. Leave the new armor style to the other sets; this would make them stand out on their own without sharing the appearance with 12 person buff sets.
