But if you're under water and you take some damage, if you take any ticks of drowning damage the person who shot you doesn't get credit for your death, you just get a suicide

Same if you fall of the map

You sure? I know this was the case in BO2, but I thought they fixed it in BO3. I'm not positive either way.

Yeah I'm in the same boat, I thought they still get credit if you fall out of the map.
I'll keep an eye on it to see if it's true

Assissted suicide

Nah watch for it in game them..
Ive yet to give an assisted suicide.

This is only while Wall Running though, No idea about just straight jumping off LOL

I always get assisted suicide with this

you get assisted suicide, yes, but that doesn't count for shit except equivalent kill xp.
--you don't get a kill on the stat sheet and you don't get scorestreak points.
