allow disabling of yourself being spectated

You're right. In this game people get themselves killed regularly in the most predictable and avoidable ways... and they will curse you, their teammate, with their dying breath because nothing that happens to them is ever their own fault. It's yours. And I'm somehow doubting that in a moment that heated you can change their perspective with spectate or killcam. You can't. You may as well have shot them in the face with your own gun. And then they quit. And don't think for a minute that this is just a Wildcard thing. It isn't. It's maybe a little more frustrating for you since you're in a mode with fast and free respawns, but it's no different in trios or bots. The one place in the game that actively penalizes quitters - ranked - still has people ragequitting. Not as many, but way more than I would have thought.
