In the Update 11.1 Release Notes I noticed this:At first I thought that this causes just a minor annoyances (while preventing exploits, presumably), like when I can not get the reward for warband quest immediately like I used to, but first have to get rid of any aggro I got while fighting the warband.Originally Posted by Sapience
But then I went back to Dunland to finish some of the quest lines I left earlier, and I noticed that some of them are now very hard if not almost impossible to finish, because of this new behavior.
I submitted a bug for a Vol. III, Book 3, Chapter 10: Echoes of the Dead instance, because there clearly the intention was that it should be possible to escape from the Cursed Oath-breakers by talking to Radanir while being attacked by them. It is now not possible to do so, as it is treated as finishing the quest while in combat, hence disallowed. It is not possible to kill the Oath-breakers either, after their morale gets low they withdraw for a moment, only to attack again with full morale a few seconds later. I finally managed to bring them down in synchronization so that I got a few precious seconds of "out of combat" state and I could finish the quest. Actually, that was an interesting challenge, but most probably unintended.
The other quest where I noticed the similar problem is Tusks of the Boar. There combat state prevents fleeing on Elder Déin's horse, but at least it is possible to kill them all and finish quest then. But that was easy for me only because my character was 15 levels above this quest.
I think that this should not be a general rule for every quest - there could be some setting, either to mark the special quests where it is allowed to finish while in combat (but that would require reviewing all the existing quests), or to mark only the ones where this is disallowed (so it would get applied to the ones where exploiting this would be possible).
Because I really hope that these specific quests stay as they were - the feeling of panic in such moments, when you have to do something to escape quickly while being attacked by overwhelming forces, can be a great experience, deepening the immersion.
