To all the people complaining about Provisioning...
There are a few simple steps to relieve your woes.
1) If you are not leveling Provisioning now on your character, do NOT loot any Provisioning items except for blue/purple recipes. Green recipes are plentiful. Provisioning mats are even more so. There is no reason to hoard them. Trust me. You will be able to find them whenever any of your alts of any level needs them. Don't save them for when you have the time. They will be available when you have the time.
2) Only save ingredients for recipes you know. I know that Garlic or Onion or Snowberry you looted looks rare. It's all green and exciting. It really isn't that rare. Rare when compared to the incredibly prevalent common Provisioning goods maybe (which is to say not rare at all). You will spend a lot of useless and ultimately frustrating time managing your pack space if you try to pick up every single ingredient and keep it until it's useful. I'm speaking for Provisioning here. I know that this is not true of Enchanting or Woodworking and it probably goes against all your MMO and even RPG instinct, but it is true of this one profession.
You see in Provisioning, you are at the whims of what special recipes you happen to find. So while you might save that onion in the hopes of finding a recipe that uses it, the truth is you might not find that recipe for a loooong time. But in the meantime you might find equally exciting blue/purple recipes that use other special ingredients instead and you won't have room for them because you're stockpiling Onions.
3) Only keep ingredients on hand for recipes you plan to use and use often.
This is really the golden rule for Provisioning, which can be further subdivided into...
- If you're leveling your Provisioner, only keep the 8 basic ingredients on hand for your current recipe level.
What do I mean by 8 basic ingredients? It will become immediately apparent to anyone actually doing Provisioning that there are 6 basic green recipes for your Alliance and skill in that profession. The drink categories at your level all have one shared ingredient. The food categories all share one ingredient as well. That's two + a more distinctive ingredient for each across 6 recipes. 8 basic ingredients.
Don't worry about having characters in other alliances and trying to save level 1 ingredients for every single lvl 1 recipe. They are merely themed duplicates that use different local ingredients but yield the same effect (buffs Magicka regen by 2 for 35 minutes for example). Your Dunmer in EP can eat Grilled Battaglir rather than his own Alliance's Fried Guar Eggs (both boost Max Stamina by 66 for 35 minutes) without suffering any ill effects. Your inventory however will have a hard time keeping up if you try to keep a regular stock of the ingredients necessary for all 3 versions of the exact same food.
- As you lvl your Provisioner, phase out ingredients. I know you're worried about having enough food to supply your low lvl alts. See point 1...Food is plentiful! That's why your inventory is always full of it. Instead of saving up lvl 20 mats for when your brand new lvl 4 can finally bug your Provisioner for food, let them go. Keep only the basic 8 for the recipes you are using to level up. Spend a few minutes in a town and you'll see that you can easily round up enough mats to make low level food for your alt when the time comes. It doesn't take nearly as long as rounding up a stack of 100 iron ore or specific alchemy ingredients, which is why saving those is more important. There is next to no competition for Provisioning ingredients specifically because they are so plentiful.
- As a Provisioner at or near maxing the skill cap, only keep mats for exceptionally useful recipes. Ask yourself if you're really going to ever use or sell it to another player. When I maxed Provisioning, I only kept ingredients for the Blue and Purple recipes I knew. That's it. If I'm not gonna eat it and no one wants to buy it, there is 0 purpose in keeping it around once my Provisioning is capped.
4) Keep a single stack of each ingredient and leave all extras behind. Really only the most in-demand recipes warrant having more than a single stack of each ingredient in your stash.
A lot more could be said about making use of the cooking fires throughout the world and in dungeons to prolong time between trips to town OR simply focusing on one or two professions at a time. While these can be helpful tips they will not fit all playstyles and they really aren't necessary steps if you learn to leave some ingredients behind in the first place.
I've seen a lot of discussion about inventory management. Provisioning seems to get called out as being unnecessarily complicated or having way too many ingredients. I even saw one post about a way to speed level Provisioning. I do not speed level. I don't have anything against it. I just don't enjoy doing it myself. Simply putting that out there so people reading this don't accuse me of somehow circumnavigating their inventory woes by way of playstyle. I like to hoard all the things too. It just doesn't make sense in this particular profession.
This is coming from spending considerable time on Provisioning both during the beta and PTS. I maxed Provisioning while also leveling the other professions simultaneously AND having alts. So believe me when I tell you that I learned all these things the hard way. Once I made the decisions to let go of ingredients, I had a lot easier time managing my inventory and I spent a lot less time staring at an overfull bank screen. Hopefully these tips will help you do the same.
