PvP icon can be missleading, making apparently safe players being able to kill.
While being alive, enable PvP, then disable it, the PvP icon remains, which makes you safe while having the PvP icon displayed for everyone.
Same thing works in the other way, have PvP disabled while being alive, enable it, and you will have no PvP icon and being able to kill people.
The icon should refresh everytime you toggle on/off PvP mode, not when dying or respawning.
PvP doesn’t refresh the icon, makes missleading about who’s being a target or not.
