Oh, no no no no no no no

NO

As for the longer answer;
Compare the isometric games of old (Baldur's Gate) with the modern games. Notice how the amount of teammates dropped drastically? That's since an over-the-shoulder camera is extremely unequipped to handle RPG's and multiple teammates.
Even if this is a lesser effect in Turn-based strategy (since, well, you got time to mess about. Why you'd WANT is another matter entirely) all the other factors come into play there. Overview. Control. Not having to fumble like an idiot with the camera to actually see something (yes, people mention Dragon Age: Origins often on this and I agree it's showcasing very well how horrid it's free-form camera is).
And look at Pillar's of Eternity. It looks *beatiful*. No 3D game (sorry, Original Sin) can come near it with it's 3D environments. Compare that to the drab horrible looks of DA:O or DA2 and I cannot phantom anyone prefering that. Worse looks, worse control and worse overview. Why would you *want* that?

Baldur's Gate realtime with pause works great. You can easily manage 8 people. Compare that to Knights of the Old Republic's realtime with pause. So you can only control your own PC and the other 2 NPC's pretty much do their own thing? Yup... pretty much that. Not exactly an advancement in combat (infact KOTOR combat is horrible).

Almost reminds me of those modern 3D RPG's where having to muck about with the camera every 10 seconds is a requirement *straight from the box*. With no way to turn it off since they made levels so absolute great that somethings always blocking your view.
So how was this worse than the full baby-sit requirement 3D camera's of other RPG's you apparently want D:OS2 to use?

which meant that in the poorly functioning mouse-look mode the graphics were full of simply awful glitches. It just made immersion impossible, and playing extremely frustrating.

You mean that they only actually made the game look good on the plane you see so if you flipped it 180 degrees it wasn't nearly as interesting. Since that would infact be design, not "glitches"... definition of a glitch is that it's an error that's not supposed to happen. Intentional design or specific intentional area of view that's not so filled if overriden would not define the term glitch. If you meant something else though, do specify please... I want to know what 'glitches' you experienced. Bit of a bugfanatic sometimes myself wink
