You'd need to get players to assume there's always another encounter possible between now and the next long rest, or at least believe that 6+ is a normal number to deal with. This is certainly possible if you always keep the pc's on a time crunch for the adventure. But no official DnD book really teaches the importance of this to dm's. So this is not the 'normal' way to play DnD.I'm not a fan of any class that can run through its daily resources in under a minutes, and paladins surpass even wizards in that capacity.
While I'd prefer to address the issue by simply making a nova strategy sub-optimal, I'm really not sure that it can be done, given the basic 5E framework.
If time isn't a limited resource, the game doesn't really work as a wargame. It can still work as a roleplaying activity, which is how a lot of people have fun when it looks like it should be horribly unbalanced.
