SFK and WC fixes were already out by the time you made this forum post. Ghostland invisible walls are not there for me. From the zones you mentioned I tested Searing Gorge which had one bug that I reported (escort quest) and the fix was out like 2 hours later. Apart from the escort quest the whole zone is working with no problems. I also went to Felwood and just completed the whole zone, again no "major issues" as you would say. I havent done dustwallow yet but considering how majority of what you said is bullshit I will not even bother to go there.
