We encounter this also, its so bad people cannot visibly see their gear swaps at times, and in some cases players appear to "warp" around which is annoying and leads to confusion. Friend of mine started to cast cure on me and the next thing he knew I was in an entirely different room. People tend to follow one leader on our routes also, and sometimes get lost because they think that person is in one area when they are actually going the other way, etc. Received is almost always around 2k.
