In the past, MVP Schwick of the European forums has solicited players for their opinions about how their class can be improved. Now he has put out a call to the readers for a list of issues concerning the Rogue class in particular.
Schwick read through all the rants, complaints and well-thought out solutions. Then he compiled the best suggestions into one post. In it he covers Rogue issues with PvE, PvP, itemization, talents, abilites and combo point abilities.
There is no guarantee that the Blizzard devs will see the list, but if they are looking for class issues, this thread would be a great place to start.
Check it out and let us know if you feel anything needs to be added.
