If you logout from Warzone even when taking NO DAMAGE on respawn you will still get warned for "statlogging" if you rejoin, as you can see in the clip below, I was warned for "statlogging" I left by accident without taking any damage as I just respawned.

This needs to change, first of all it makes no sense to why you do it like that. I think "statlogging" should and can be fixed, if a player logs out while having taken damage since respawning they just give the attacker the kill and add a death to the "statlogger" or if a player logs out and rejoins a DIFFERENT team then that should get classed as statlogging.
