I like Elden Root for several reasons. First and foremost, its a TREE! Secondly, absolutely everything is there, from writ turn ins, to MG/FG to Undaunted Enclave. Thirdly, Snugpod is a wonderful little home with a great location.

Only downsides to Elden Root are that it is a bit spread out and is too crowded.

Vivec first, Leyawiin second.

Vivec because all the crafting writ boards, crafting stations, writ turn ins, and bank are really close to each other and the bank has no loading screen. Also, there's a guild trader hub nearby too right outside the crafting area.

Vivec is the fastest most convenient place to do crafting dailies and banking/inventory management. I wish more city hubs were made like this.

Rimmen 100%, because the outfit station is right there, and everything is outdoors except the bank. In Vivec, the outfit station is too far away in Vivec's Labyrinth of Noneuclidian Floorplans. Canton? More like Can't Run to the dye station.

I suppose the same benefits apply to Leyawiin, but there aren't natural hangout spots by the wayshrine like in Rimmen. In Rimmen, the crafting path pulls everyone past the fountain and the carpets make a natural stage, and there's often music and dance. I hope they design more cities with natural hangout spots like that.

It depends on what we mean by "best". My characters do their crafting in various areas, and some of these are scarcely populated, which suits me fine. e.g. my orsimer does writs in Orsinium, and almost never sees anyone else while doing them.

Functionally speaking, I prefer Vivec, Alinor, Rawl'kha. If I'm doing anything outfit or guild trader related, I stick to Alinor. If it's a newbie character or I need quick guild bank access, Vivec. Purely from a crafting perspective, they're both great. Super quick station layout and turn-in nearby. Vivec used to have some NPC in the way and they fixed that a few patches ago. Rawl'kha has everything outdoors and is quick to get to with the Sleek Creek House.

I would use Blackwood more but the turn-in for crafting writs is awkward. They're up on this cart and my character just walks in place for a few seconds before opening the crate to turn in the writ. High Isle had this problem too.

Rimmen's not bad either, but I find the crafting area too busy and the turn-ins are too far away. I like the nearby outfit station. I'll switch it up every now and then and do them here.

I prefer Vivec for my general crafting/writ location, and since I am not just doing crafting, the outside bank/guild bank and guild traders, horse training, and event merchant are all right there. The only issue I have with Vivec is that the inn house and outfit station are two cantons over.

Rimmen is a nice second, but it is spread out a lot and the bank is behind a door. Bonus is there is a house right next to the wayshrine. If the Northern Elsweyr quests have not been done, I have to listen to that lady complain about the monks chasing butterflies, though. It's not as bad as "dragons in my homeland".

Leyawiin has a reasonably close inn house, but the stairs are a pain. The bank is behind a door, as well. Bonus is that the outfit station is right with the crafting areas. It would be better if there were fewer carts around the blacksmith and woodworker, though. I get hung up on them more often than I care to admit.

What is the best place for writs, writ turn in, and a horse stable? I don't care how far the bank is because I have the assistant.
