@ Horrorscope; ALL OF THAT has been fixed already. All of it. Seriously.
There's no need to patch it up, all of that has been resolved already.

Actually, going to other forums there's a major amount of praise for PC's avoiding traps and hazardous environments by themselves, wondering why other games couldn't do so.

While that's "wow" for new players, it has somewhat a different meaning to those of us who indeed saw those issues and lost our team to that many many times.
But as I said, it has all been fixed. So there's no reason why people should still encounter it, unless their patches screwed up something... which verify would fix.
