The task was to craft a pair of imperial style leather boots. I crafted those boots with the correct trait and material, but converted them to imperial, because I have the Imperial Edition of ESO, and then improved them to epic. But the quest step still says to craft the boots.
There are two problems in my oppinion:
1. As for the Imperial Edition, I expected to have all advantages that come with the abillity to convert everything to imperial style.
2. Imperial style is still one of the rarest/most expensive styles in the game, but this master writ grants only 6 vouchers (compared to nirnhoned items for 50+ vouchers)
