Combat/Out of combat attacking npc or players

[mnclaras]

I have detected (in dummies) that if I am hitting the dummy and another character is hitting the dummy as well, when I stop hitting, the combat never goes away until the other person stops attacking him or attacks another npc (I understand that it will also pass attacking players).

If other players do AoE damage and they touched who you were attacking, it will also not cause the combat to go away.
This should work in such a way that if you stop attacking the player or the NPC, you must go out of combat, regardless of someone else hitting.

Do you also have this bad behavior?
