I have a 42+ weaver, and I'll admit, I never set up a retainer in the wards. I leave them on standby so I can call them at the bells.
The stuff I do sell is only in my bazaar, and it's usually a pretty limited selection. Mostly a couple hot ticket velvet or linen items, usually the crafting stat ones, like coatees, shortgloves, colored cotton undies, and random HQ stuff. It's really just stuff I make on impulse, and if it sells well I'll make a couple more.
Do I go out of my way to keep a large stock of all lvl items for all classes? Of course not... I have hardly any space as it is, and with no mailbox, muling is a huge pain.
But there is an upside for those people in search of items. I do free synths for everyone I know or who is in my linkshell, and for anyone random who sends me a /tell, I'll do the synth for free, but accept tips should they feel like giving one. I usually have the cloth mats laying around, but some gear needs stuff like a buckle or other oddity that I'll ask them to provide. Likewise, if you round up all the mats yourself, I'll happily do a free synth. I know crafters of each field who do the same on my server too.
So really, it boils down to this... The market wards still suck, and you need to actually contact people if you want to get anywhere. I rarely ever go to the wards. Even if what you need is there, it's either in the wrong ward, killing the ability to search for it... Or it's marked up at a 5000% profit margin due to SE's not so brilliant idea about thwarting undercutting.
Undercutting is a **** good thing, and this is coming from a veteran crafter of both FF mmo's. Trying to stop it ruins the supply and demand system, and leads to everyone just being lazy and making a couple hot items, and overcharging for them. Why bother going through a lot of extra hassle to make several items that don't sell as fast or for as much, when you can just run the same bazaar as everyone else, because nobody can find any of the other sellers anyway?
My point is, be nice to people and make friends, the bigger your network is, the more likely you are to be able to find what you need. And keep pestering SE about adding in an AH. It's not the crafters fault that it's hard to find things, they are just taking the path of least resistance to meet their goals, and as long as they are still progressing and making gil, there is no reason or incentive for them to take a much more tedious and time consuming path to get to the same place.
