SE could make Clusters that grant 99 crystals when used drop off Elementals. Maybe the ones in Abyssea's.
This would kill the crystal market.
For the stacks of 13-98 etc.. it would work like any other stack you cannot sell them if they don't equal a full stack or1.
We're then back to needing more AH slots as it's either 1 or 99 for the seller. Crystal market, or any market for that matter, suffers
However I do like the idea of the option of selling them either as 1 12 or 99 on AH but then again 1 or 99 seems less stressful on the AH.
See above, but consider the "quiver" angle is basically making stacks of 144 with a dozen 12s.
As far as paying more for stacks of echo drops, it all ends up panning out in the long run anyways. You would end up paying not much different if you were to buy roughly the same amount. It could be cheaper to buy a stack of 99 though vs. buying multiple stacks. The price would just balance itself out like it does now. Just at a higher price./ higher quantity. Raising the material item stacks to 99 would be a godsend to crafters.
Can't agree. I endured the change of bolt/arrow heads and fletchings from 12 to 99. It might have made the lives of woodworkers easier, but as someone who sold bolt heads, having to do 17 synths to make a stack instead of 2 meant more money was needed to prepare the batch, more time to make it, more risks of breaks, and eventually slower sales as the sale rate of ammo didn't change, just as I don't expect people to use more echo drops just because they can hold more. Once you get past the initial rush of newness, Alchemists will suffer.
