Thank you benzviliran for not avoiding the fact i may be logged out. i just Pity the Fool who's illogical.
i left the combat and opened menu game and clicked on (exit game) you need 20 sec to leave game but you can cut that, there's two opinions appear for you to choose one of them if you want, 1- exit now, 2- cancel, i chossed (exit now), and seems i didn't log out immediately since you was able to attack me, but since i wasn't move or do any spell, that mean i wasn't in game but my character is still there, i wouldn't risk to do alt f4 while i am under attack, i know already i will log in and i will find my character died.
but i see you are talking about the fact i may used some bugs to leave combat, well its pvp my friend, i mean if your pvp enemy stop attacking you for a time, you will leave combat even if he is close from you, it isn't like pve world, when you attack some mobs and you could be near them but they doesn't attack you, you will still be in combat, just need specific distance to leave combat, but about pvp, you don't need a distance, it just need Time to leave combat.
Don't hurt your friends, they are a reflections of you soul:)
