It just flat out doesn't make any sense.
-If I am solo and kill a player I can usually sneak immediately... but not always.
-If I am solo and don't kill my target I usually can't sneak...but not always.
-If I am in a group and kill a player and get the killing blow i can sneak immediately but if I don't get the killing blow I am stuck for 30 seconds...but not always.
-Sometimes I'll be in a group and be fighting and not kill anyone and still can sneak right away.
-Sometimes in a group we kill all the enemy players and no one can sneak for 30s.
It just doesn't make sense... I would LOVE to actually be able to know 100% that I will or won't be able to sneak, but right now there is no logic to it. Every time I think I've figured it out I'll end up either being able to sneak right away when I usually couldn't or I'll get stuck revealed for seemingly no reason.
Personally, I think if you are out of LOS of any enemy you should always be able to sneak. For now though, I'd just like to know how the system is actually working because it feels incredibly random.
