It's one thing to have a downsized crafting system, if the devs want the focus to be on story and role-playing, but that's different from having an incomplete or unfinished crafting system. If you want to buy a cheaper car, you still want it to come with 4 wheels.
If we can craft minor stat potions, we should be able to craft the better ones, just like we can for the other potions, runes, etc.
