I think it's both - a good feature and a cop-out. It lets you get away with including more battles than your player deems fun by reducing most of the pain involved, but it also masks the problem of "the battles aren't fun (anymore) for the player" rather than actually solving that problem.
In an ideal situation the battles will never get boring for the player - in practice, even fun battles might not be appreciated by all players, and if your dungeons, world, and objectives aren't straightforward enough, some players (like me!) will get lost occasionally, and won't want to be constantly distracted with battle tactics as they get their bearings. So I think such a feature is welcome in most games it appears in, for the times where the player doesn't see the appeal in participating in a battle.
