I said it would slow down game play because if you had to open your inventory every time you ran out of ammunition to pop an ammo synth, it would definitely slow game play. I said that in my statement about if there were no ammo drops from aliens. I'm fine if they added them back into the game, but didn't let players buy them or hold onto stacks. Let me explain. Ammo drops are all around on the ground right? You're guns are full of ammo, but you can automatically pick up one of each ammo pack to automatically use later when your gun reaches the halfway point for ammo. Your guardian would take a little it longer to reload, maybe shown in a slightly different reload animation. This enables you to carry more ammo for everything, while not letting you stack power ammo like back in the D1 days. This probably wouldn't be easy to implement into the game though. EDIT: Awful idea now that I've thought over it more. Disregard.
