Completed the Clothier writ today for the first time. I was highly disppointed that the survey map only offered light cloth materials and no leather at all. I understand there are no "leather nodes" to gather, but--imo--they should offer some rich animal carcasses that give plentiful amounts of leather when looted.
I haven't used any light armor for my main character and don't plan to. If the clothier surveys don't offer leather, then I don't have much use to take the time searching for the location. Just seems shortsighted for Zenimax to not have thought about this.
To be fair I have only completed one survey. If clothier surveys do have a chance to offer more leather, then I'd be happy to hear about it.
