I do have a beef with this too. I bought a perk called throwing knives and... there are no “throwing” knives! You throw your regular knife and you can’t pick it up again. You lose the knife.
Wouldn't that mean going through the inventory system every time I want to throw more than a knife or two? That seems irrationally clunky. Like making someone use a menu for cut and paste.
Crafting is in a really fucked up place, its true... you can only craft a single item at a time, which is strange because eventually you can craft consumables (grenades, autodoc items, etc.).
I should be able to input a number of knives I want to craft, hit the craft button, and boom, I have 20 knives.
Ammo clips too. Now every 10 minutes I have to stop so I can hold the A button for 2-3 seconds for each of the about a dozen clips I need. It's super boring.
