Guild Wars 2

Setting aside the larger issues that exist, as I was jumping ever upward on a puzzle today, some questions came to mind.
The question I have is in regards to those little adjustments that are more of an issue of polishing the game than fixing bugs or adding content.
Using jump puzzles and vistas for an example, there are a number of cases I’ve come across where the landing point on a jump seems like it could have been done better. Something to give it a more solid look than a random leap at an edge that comes out a little further than it visually appears to.
What sort of resources have to be changed in order for a change to be made to correct something, if it is seen as a problem?
I don’t want to assume that it’s all just a matter of moving an edge or two on the mesh structure of the object then queuing that newly modified object up as part of the next patch download. What else has to take place in order for a “fix” to be made?
Does Arenanet want players to file bug reports when they find something that doesn’t quite match up?

I’d like the camera to not randomly go up my norns butt…. does this count as a little thing considering how massive norns are ?
