I already thought that most collectible items are rare, considering most people have always just let them stay on the ground. The crafting system was largely good as is; I can see making changes to the unbound shard crafting; I have only some reservation with changing that, but I really fail to see the problem with bound crafting AS IS.
Bad idea, bad implementation, bad everything.
Decisions like this end games. Literally. I know someone here can point out numerous "changes" MMOs made to their games that ended their lifecycle.
