Just finished 5 dailies on Operation Shieldwall with my hunter, before I could turn them in they reset and were taken out of my quest log. This shouldn't happen at 7 am in the morning. In the past I've been able to turn in dailies even the next day. I don't like this change and Blizzard should reverse this from happening.
Daily quest resets don't remove quest..
Some faction's quests are indeed removed from your quest log - Golden Lotus for one, and Operation: Shieldwall/Dominance Offensive as well. I believe just about all others you can keep and turn in for the next daily reset, although I haven't tried with the new island dailies yet. In any event, it seems the only way to avoid the problem is to turn in dailies for those two factions well ahead of reset time.
