My few suggestions for Expeditions

1. Recombinator always turns items into Rare. I think it would be nice if under some conditions it could remain magic. For example if two items it recombined are magic or even harsher rule, if you combine two magic items and one has only prefix taken and second only suffix, allowing you to combine the two into new magic item with two of these mods on it.
Thanks to that You could use Essence on it and get yourself decent mid-tier items.

2. When buying Expedition items from Vendors, when they ask if we want to craft on it, allow us to select from option of 2 to 3 choices.
