What about turning off dungeon alert? At least temporarily?
Aggro sharing is acting weird and needs fix, red alert is still causing instance lag and near or full party wipes (2 days ago in slavers)
Quest design lean towards advancement via killing mobs or the door won't open, puling levers and such.
Just an example, in the quest "Sunrise" my rogue said "leave that to me" after spotting a key on the ground. Counted as an action, picking it up broke stealth. (personal note: i felt like a deluded idiot). Killing - activation progress mechanic, see above, all the new quests and i guess the upcoming ones will be this way.
Maybe it's time to forget DA for good or disable it temporarily until some fix? Since you can't go on with no kills...
EDIT: a good example is how to curse the sky was changed with added gates
Please discuss.
(But pretty please do not discuss about sneak and no thanks i don't need sneak explained, that's not what's the post is about, let's stay on topic, that is DA problems and quest progress)
