That is a great way of looking at it.Here's a different way of looking at it that might help. Let's say you as the DM plan out an encounter in a fun location with a particular difficulty level in mind, and then the PCs spend 30 minutes of real time trying to lure the enemies onto a different battlefield where the PCs would have a tactical advantage.
At your table, would these PCs be playing the game exactly as intended, or by refusing to engage with the encounter as presented by the DM, are they being disruptive? The former would be more indicative of a Combat as War game. The latter would be more indicative of a Combat as Sport game.
And it's also why agreement at the table on "how we play" is super important. I prefer combat as war, but there is no "right" way to play. There are "wrong" ways to play, and groups where one part of the party is bored by the planning and scheming, and one part of the party is upset by the barbarian just charging in and throwing the plan in the garbage.... that's not fun, and that is "wrong".
