idea: better loot for SSF, but drops are soulbound

Hello.
I find the experience of finding loot myself more enjoyable than buying it in the auction house. However I also noticed that crafting is not so much accessible when playing SSF. Specific crafting materials are hard to get and even generic crafting materials take quite a lot of farm to get in larger quantities.
I have the impression the crafting system is designed to be used together with the currency exchange (to buy the particular crafting resources you need there).
My idea would be to increase the drop rate in SSF - the most important would be the crafting materials - and make everything you find in SSF soulbound (meaning they can not be traded with other players, even if changing later to a trading league). I'm pretty sure some other things could benefits from a drop rate buff in SSF as well and/or they could offer us a way to target farm certain things - certain builds need certain items.
