So then whatever the Fighter/Warlock/Monk wants is just? There can never be a situation where players of short-rest classes want to do something unreasonable or unfair? They always act rightly and nobly, without error or misjudgment, and should always be forgiven and given allowances, even unto the failure of the adventure, lest they endure even one encounter without their full capabilities? We could continue to the docks before the ship holding the hostages leaves port, but, no, the Warlock needs her spells.
See? I can be hyperbolic and unrealistic, too.
Stop imagining that everyone who disagrees with you is doing so out of dishonesty or injustice or a desire to personally injure you.
