I started to do Writs and find that they are keep asking to make the same things and the reward don't give me the style pieces. It's nice that they supply the material for the lowest level Writs but not the high level ones.
I also find that the higher Writs don't ever give back the material that the writs require. The writs require the highest material I can use but the boxes are always for a lower level material.
Seems like the higher level Writs are not worth the effort.
I also find that the Writs for enchanting always ask for the potency jora stone but never give it back and I am running out of them. Enchanting also only ever ask for stamina, magicka and health runes.
Alchemy also has only like three types of potions it asks for.
Doesn't seem to be very well done or very limited.
