I dont think that most people realize this. Shehie can npced for ~25gill each. 25*99*12=29,700. Thats nearly 30k for npcing a stack of toolbags (without bundling price).
The reasons for these fluctuating in price so much are very simple.
Supply and demand - Conquest tie - and the true crafters.
True crafting of this item is very time consuming. For the cheapest and most efficient way to produce these for a crafter is to make their own ingredients. However these are acquired from all across the world, not one simple location.
This also means that since your making all the ingredients that your doing 3x the synthing to produce a single shihei synth. Also to increase productivity certain synths are best done on certain days of the week. All together this takes a lot of time to do properly. The only other option is to by the mets directly and synth which will cost a LOT more gill.
You're saying all characters that either don't have a profile on ffxiah.com or are lvl 1 are RMT...
You sir are an ***. People make jeuno mules constantly, people don't always sign up to ffxiah, people sometimes don't have a laptop/pc if they play on console, theres a million different reasons.
You are no different to people who are a victim of good business/economics and then throw a paddy and scream RMT RMT!
It's not uncommon for people to make crafting alts or to dump items onto a mule to sell. This is why there are so many empty level 1 profiles that sell expensive items. Mule =/= RMT.
Seems to be the number 1 item for RMTs at the moment - people with woodworking lvl'd are probably making other things to make more profit, not sure ... But it seems the same ppl keep smashing out 20 toolbags a day n ***.. Ppl need to stop buying and make their own - or get a friend to do you some!
