The play style where the player are highly cautios and focus on their survival changes, using their best resources against enemies to minimize personal risk and choose to rest safely early and often (e.g. 15 minute adventuring days), story consequences be damned. Under this play style, characters without daily resources are weak, since they do not have any powerful resources they spend early.
Or a play style where little combat actually happens each day, as the characters are busy with non-combat activity (possibly to set up a major combat, maybe independent of that), where again, casters (meaning every class with major daily resources) dominate.
Or a play style where characters are expected to run through many combat encounters during the day, so many that spells will feel unnecessary and the spellcasters have little to do or run out of spells early, where non-casters dominate.
Or a play style that wants the freedom to switch, based on other demands - player mood, story or whatever - between these modes, but without doing each equally often or switch regularly (meaning that either there could be long rows of "boredom" for some players, over several session, or that over the course of the campaign, one variant dominated and benefitted the according group of characters).
