That's not what I'm sayng.An encounter doesnt have to drain resources to be an encounter. It only has to potentially drain resources.
If the PCs can overcome it with Skill checks, cantrips or at will abilities, so much the better for them.
I andothers are saying that 5e is designed to have the PCs deal with 6-8 encounters a day in order for at-will, short rest, and long rest abilities to have parity.
Any encounter that does no drain a noticeable amount of resources does not count to that 6-8 encounters needed for balance.
If you talk to an NPC and use 5% of you spells and superiority dice reaching them, buffing yourself, and countering obstacles, the encounter counts against you ~7 encounters.
If you simply walk over to the NPC and make 2 Cha checks and walk away, it doesn't.
Well...Which is a terrible design choice if true (and you have no evidence it is true by the way, just your assumption).
I find rocket tag to be boring and deeply unsatisfying.
WOTC realized that most groups don't go through 6-8 encounters so they experimented shifting features from 1/Short Rest to Prof/Long Rest to let PC nova in 3 encounters.
