Crafting Guildleves Requires "Guild" support in cities that don't have that guild.

Culinarian guildleve "Finger food" in Uldah and one in Gridania both give a message about needing "Guild Support". Everytime I get this I either fail the item or have to "hasty hand" it to get it done. You can only get common support in grid and uldah, have to go to LL to get guild or master's.

The alternative is to remember to get support in LL, but why should I start every time in that city? I'm not always there. Otherwise it is Uldah->LL->Uldah. Doing these leves burn enough time and anima as it is.

I even bought the breadbaking book the item requires, specifically because of this, and I still cant complete the craft being 4 ranks higher than it.

FIX THIS FOR THE LOVE OF ALL THAT IS HOLY. that is all.

Usually have no difficulty (maybe a break or 2) finishing leves up to 6-7 ranks above me with Basic support.
Inappropriate equipments?

OP is correct IMHO. A good deal of culinarian items require guild support, many of them leve items. Trying them without the support, even significantly above the level of the synth, is difficult at best. Which means you can expect to travel to Limsa to do your leves as a culinarian.

The real problem, as I see it, is just how many culinarian items require guild support. I can make exotic growth formulas and intricate armor until the cows come home anywhere I please, but the twelve forbid I make some butter without guild facilities.

I agree it does suck not getting guild support when you aren't in the city that supports it. I do Armorer and Goldsmithing. I spend most of my time in Ul'dah and can't afford the Anima to get to Limsa if I need 60 mins of Armorer support. On most things I don't have an issue completing a synth without the "required" support. But on things that I can actually get good SP on, it makes a huge difference on success. My most recent example is that I wanted to make some Iron Nugget with Blacksmith, so I could make Iron Square for Armorer. The Nuggets take Guild Support to improve success.

I can understand why the option isn't there. Why would a camp have the same Equipment as a Guild? If you want that kind of support you gotta go to the source. At least we can get Common Support from anywhere. Honestly, if it's not believable I'd rather not have it. There really shouldn't be the option to get Guild or Master support from anywhere other than the Guilds. Thank you SE for not spoon feeding us.

This has been an annoyance of mine as well. The goldsmith leve 2 x 2 Eyes in Limsa requires guild support, but the guild is in Ul'dah. So after I get the leve I go get the materials from the NPC and then do the actual crafting later when I am in Ul'dah. Of course, then I have to remember to deliver it next time I am in Limsa (before picking up new leves), and this would be quite inconvenient if I actually could find 8 rank appropriate crafting leves to fill my journal with each reset.

There are plenty of recipes that do not require guild support, so why not just use those for crafting leves in cities without the guild?

Umm...unless they ninja changed it, the game ignores you not having the proper support or training for leve synths. I'll have to go back to the lodestone to find the post, but it was quite explicitly stated to be that way. That doesn't mean that guild facilities won't help in a general way, but if you're doing a synth for a leve and it says it requires a particular facility or specific training, it can safely be ignored.

On an unrelated (maybe) note, I have been having more issues with synthing in general lately, support or no. I've gone on runs where I don't fail a single synth for something 5 levels above me, but I can't complete something at my level to save my life. No training or facility requirements at all.

If that is true, Suzaku, that really hasn't been my experience. Any leve I do that requires support for the synthed item is very difficult for me to complete without the correct support on. So I have to give up after the first few tries before I risk not being able to complete the leve and wait until I can get the support. As soon as I do, boom, easy peasy.

Huh. I have not had any issues with leve recipes requiring support that I haven't had on same level leves that don't.

I did do some poking around the lodestone and couldn't find the statement in question. I am completely positive that I saw it--and my own experience with crafting does back it up--but there is always the chance of me being crazy.

Well, crazier than normal.

You can get basic support from the Repair NPC (Choose 2nd option from the initial question they ask you). Its the same support that is offered out at the camps. If you need Guild or Master support, then it does sorta make sense you need to go to those guilds. Eitherway, I've found very few synths worth leveling up on that you couldn't either A) grind through with proper books or crafting abilities. or B) level up on a different synth.

You can get support from repair npcs, just choose the option 'I'd like to repair my own items'. Make sure you are the proper class before selecting that though.
That's definitely not the case Suzaku, though on syntheses that are lower than your rank you can get away without support when it asks for it. There's a noticeable difference in doing a synth with support when it requires it and not having it. The same goes with training.
