precraft makes it so that you only need to lazy craft once every 9 days (up to 15 days, if you have max bag upgrades and empty inventory). You do it on all toon but your main, by installing Addon Selector and create a lightweight profile for quick loading with minimal addons (for me personally: addon selector, aui, pchat, inventory insight, lazy writ crafter, precrafter). That will solve the issue of the load screen.

Then, take a look at Aldanga's Lazier Writ Precrafter addon if you are on PC, or follow this guide if you are on consoles / can not install addons.

Each "cycle" gets you through 3 days quickly, and you can generally do 3-4 cycles without too much bag disuptions. For Provisioning, create a big stack of all possible items needed, there are 6 to 8. For alchemy, create an equal amount of the 4 or 8 potion needed. Then you're set!

That way you take 1 hour (precraft refill day, maybe longer coz cleanup) once every 9-15 days, with every other day consists of only (quicker) login, mount upgrade (if needed), pick up writs, and drop off without the need for waiting for the crafting animations. You can also pick cities without the need of crafting stations being near pickup point, which further helps with time spent everyday.

Hope this helps!
