When I played 4E with my old group, we didn't nova during regular fights, but we did use the occasisional daily if it made sense and helped us pace the fights better. Maybe everyone didn't have 4 dailies in the final fight, but you still got a few healing surges left...
I saw multiple different daily strategies in 4e.
I saw people who used their biggest strongest powers immediately everytime. They wanted to shine and use their coolest powers.
I saw people hoard all their daily resources for what they thought would be either the end boss or emergency situations.
I saw people ration out their daily resources trying to judge the toughness of the current encounter and the expected encounters of the day to efficiently use powers throughout the day (using powers earlier to end fights earlier and save healing resources for later in the day, etc.).
I saw people metagame that travelling encounters or other types of situations would not be multiple encounters in a day so use more daily resources to bigger nova in each encounter to match the expected fewer daily encounters.
I saw people use situational daily utility powers as they became relevant based on situations.
I saw people decide that one daily per encounter was about right and generally stick with that.
I saw mixes of strategies in parties.
I also saw some frustrations with dailies.
I saw the Nova immediately PC who liked to roll big damage get frustrated as encounters continued and they went down in effectiveness.
I saw the hoarding strategy get frustrated when a boss was not reached and they hoarded when it would have been better or more fun to use fun resources that instead went unused.
I saw people get frustrated at trying to measure out dailies and get the judgment wrong for the situations that came up.
I saw some frustration at being incentivized to think about the adventuring day and expected encounters rather than the specific situations at hand. The whole party novaing a wilderness travel random encounter in the middle of a weeks long journey while dungeon end bosses being climactic fights with fewer party big guns for novaing because of attrition uses earlier in the adventuring day felt off.
