This will be the first thing to notice about this 2.0 on release, "The oppression of Final Fantasy XIV".
There is a substantial amount of loss from this idea. The amount of people that already hate this idea is just the beginning.
Taking away freedom and choice to sell/share/trade used gear is appauling and will dramatically damage the launch of 2.0.
There is too much to lose and nothing to gain. I don't believe that anyone asked for gear binding and yet hundreds and thousands of people will despise it to the point they wont see any point in playing this game. I was waiting for PS3 so I could play with even more of my friends and share equipment. I wished for a mail-box system and Auction house.
I am a crafter and the same rules will apply, high quality items get put back into circulation or experimented on and normal quality gear is easy to scrap. There is already too much unique/untradable gear that is getting thrown out because it was not even capable of turning into materia. Selling to an npc is a joke and turning to materia should be a choice.
Almost everyone does the math and considers downgrading and selling all there gear at one point for one very rare piece of gear that they waited one year to find an opportunity to buy.
A better solution for a strong flow of crafting and use for all the synth recipes/drops then create a demand from NPC's as some part of a different award system. Because most crafted items were useless anyways and tons of gear is found just from playing so buying from crafters was not necessary. That is untill they can produce a double or triple meld.
If leveling up to 50 wasn't so rediculously easy players may have taken pride in keeping HQ or multi melded low level gear, as well love to know they could share those low level pieces with a close friend. It's the whole point of an MMO.
I said it in my first post, it is imperative.
The problems with the first attempt to launch FFXIV were so obvious, character binding items is one of these obvious problems.
