So you hit with A and you pickup/interact with A button, I really would like to me able to bind the pickup/interact A button. Why is this not possible?
Remove skills from A. I have no skills bound the pickup/interact button and it solves that problem 
Yeah I know, but still why is everything else bindable but not this? 
Under the skill tree, general tab there is a skill for loot and interact. You can bind them to a specific button there.
Can’t, it just says “Note: Pressing A interacts/Loots in addition to performing bound skill”
