I am a moderately experienced player of RPG's I've enjoyed Planescape Torment and the Witcher series a great deal. The Neverwinter OC interface is driving me crazy. Switching views, dollying my characters around, dealing with bad NPC AI, I'm sure you've heard it all.
Can I jump to Westgate, Zehir or Mask..." and have a better experience? Do I have to slog through the OC in order for the other modules to work?
I don't want to chuck the whole game, but I'm not having very much fun.
What do you experienced folk think?

The camera and AI don't get any better. They are the game's biggest and most glaring faults. That said, the other campaigns are all much better-designed than the OC so it's much easier to get over that finicky camera when playing them.

You can jump into any of the campaign's directly. Even though Mask of the Betrayer picks up where the OC leaves off, most of the plot threads from the original are irrelevant to the sequel. Storm of Zehir and Mysteries of Westgate are stand-alone and unrelated to the original story so you can just jump into those.

If your having trouble with the Camera , UI, & controlling NPC's, then changing modules won't help.
Small adjustments in the control options can make a world of difference.
I only play in character mode & rarely switch views. There's a pic of my character mode settings you could try.

How far into the OC are you?
