no daily quests (as known in games like WoW) don't have multiple outcomes. They don't have follow-up events which depend on the outcome of the previous event. Daily quests don't happen if there is no player near them, so bandits always wait for a player to attack a village or they are already there. You don't see it happen. The area is always the same, with the exception of phasing, which destroys the possibility to play with every other player in the area. Daily Quests are not about cooperation, you have to steal enemies from other players to get your loot. In GW2 there is no need to form a party for open world events, you cooperate with everyone just by being there and taking action. You can't grief events for other players.
