After playing with chamber a little bit, I feel like there's a simple quality of life change that could be done.

When you run out of bullets with the headhunter or ultimate, it will swap back to whatever you last had equipped, as if you had just used an ability. However unlike a lot of abilities you will be swapping back and forth between your knife and headhunter or ultimate. Obviously this is avoided by just learning to pull out your weapon when you run out of bullets so you aren't left in the open with your knife. However I feel like in this case, there's little reason to want to swap to your knife immediately after running out of bullets.

Anytime you are using your last few bullets, you will almost always want to swap to another gun after running out. I think in this case it should swap to your secondary, or primary first if you have one. The same is true for defusing and some other abilities like yoru ult, it only makes sense to default to equipping a weapon over your knife. Though we could all just get used to this, I feel like it's something val includes in other agents to make them more intuitive and less confusing.
