While i think crafters shouldn't be able to make top gear on par with stuff you get in high pve content, it would be nice if they could figure out a way(i have no ideas though) that crafters could enhance/modify that same pve gear giving more purpose to gear crafting classes.
THIS would result in "enchanted gear or bust" WoW-style. Because that's exactly what you described.

I'd rather have crafted bind-on-pickup gear equivalent to tome gear (and BiS or almost with full forbidden meld) with mats dropping in the top content (T6-9 drops), and being untradable. Horizontal progression. Coil drops should be on par or slightly better than those, so no one "has to level a crafter", but it does give an option for those who are.
