I get what you mean. I am ok with instanced areas too but there's many times where I've tried jumping down off a ledge where I know for a fact I can walk below, only to be blocked by an invisible wall. It's irritating to say the least, if only for the fact that it ruins immersion. Plus every once in a while I'd like to be able to fall off a cliff and die instead of supermanning once I hit the ground(this leaving me at 1HP crap is ridiculous). I know that sounds stupid but if I can take just as much damage at 100m as I do at 1000m that is just confusing.

It's all nitpicking really but when you run into these things you are just like "Seriously!?"
