If I am in a party, I always vote for doing yet another encounter, as long as there are a few healing surges left. So I am always interested in daily item powers, since we regularly try to get three or four milestones. (We do not take an extended rest automatically between gaming sessions, just a short rest often.)
For example, our current party has fought its way past ambushes and encounters on a long road to the mountain fastness of a kobold dragon-worshipping cult. Now we are trying to hunt down the wyrmling blue dragon, after having made it retreat once already. Nor shall we rest until we slay it or die trying. (Crosses fingers.)
Mind you, we have almost no daily magic items at this point, this dragon's hoard being our hope for a well-deserved reward.
