Of course, when blatant graphic problems are around for months at a time, they can be a bit unnerving. It really lends itself to the school of thought that ANet doesn't even take characters through their own campaigns anymore.
For example, I just took a new Paragon through all the campaigns. I was shocked to find that the bridge to the 3rd Emissary of Dhuum in the NF Gate of Pain mission (ie. the Masters) is still missing. I first noticed this a few months ago, at least.
Right in front of where I'm standing there is supposed to be one of those glowy yellow bridges that leads over to that Emissary of Dhuum in the distance. Granted, I knew from prior experience that the bridge was there, so I knew where to walk, but new players may get PO'ed and confused.
For reference, here's the pic I took of the same spot a few months ago:
Yeah, I guess I could've reported this in the bugs forum or something, but I figured that somebody at ANet would've seen this by now. Hell,
anyone who plays Gate of Pain and goes for bonus would've noticed it. FWIW, I've used both ATI and nVidia drivers, reinstalls of GW.dat, etc., and same thing.
