So full attacks eat your swift action now. I can see why they did this, but it annoys me that you can't quick-draw a weapon and then full attack with it in the same round.
This makes quick-draw pretty useless because you can always draw your other weapon while moving anyway.
I was planning to have my solider carry a grenade launcher for utility situations and use the called fusion to swap when needed, but now I am sad.
The advantage of Quick Draw now seems to be Thrown Weapons, which it now lets you draw and throw as the same action, meaning you can go from unarmed to full-attacking with them easily. Other than that, and maybe drawing two weapons on the same turn while still getting an attack off, it's pretty much useless yeah.
