On top of that D&D is sadly a combat focused RPG - you see it in the class progression and focus on combat abilities.
For martial classes, yes. But arcane and divine spellcasters, rogues have lots of non-combat abilities. For example assasination rogue lvl 9 and 13 features are about infiltration and creating false identities rather than raw combat strength. Also almost every skill is used mostly for exploration or social encounters instead of combat. If DM lacks imagination and can only do dungeon crawl campaigns it's his lack of imagination that turns DnD party into a tactical wargame.
