Guild Wars 2 has some camera smoothing built into it. It is generally more intrusive than it needs to be, but it also has a bug with it that makes it feel really bad for people with specific mouse look styles, like mine
. This bug, and reducing the amount of smoothing is being actively looked at, but must be done carefully and tested carefully as its impact will effect every single player. Thanks for your patience.

p.s. These are not the only camera issues, but are far and away the most egregious so we will address them first.

Thanks for your understanding.
