Of course. I find them incredibly useful. Sometimes.

Well, that's what you have to default to in some of those areas where the hallways are narrow or it's a maze-like structure. That's kind of the complaint.

It's tedious. There are certainly times where you want to scout ahead and pull up your party one member at a time. But not always. For example, I'm going through Durlag's Tower right now and I can tell you it's an enormous pain to try moving your party through areas you've already cleared and one or two wander off the long way and end up running into one of the respawning areas. I've actually taken to using the console cheat to jump them to where I want to be in areas I've cleared instead of going through the hassle of walking them there.

It's not even the pathfinding that sucks, it's the fact that every single time your party members bump into an object, they stand in place for a second or two before moving again. This means that in closed spaces or areas with lots of NPCs, you have to micromanage constantly just to perform even the most mundane of tasks like, I don't know, walking through a door. It'd be simple to fix the problem by letting your party members pass through each other outside of combat, which Baldur's Gate II might have done (I can't recall). Either way it was a really dumb oversight for BioWare to make.
