This conversation is a “damned if they do, damned if they don’t”.
If Devs play at a high level, they’ll be accused of designing only for a high level and ignoring low level/casual players.
If Devs don’t play at a high level, they’ll be accused of having no clue on the game they’re designing for.
No matter the playstyle of devs, if it’s known, it’ll be used as a bludgeon from players with an axe to grind.
