Don't answer terrible posts, report them.
Based on my race and professions... 4pc is pulling head by 34 dps of 2pc. Of course, depending on your professions and race this changes. For instance, I am getting 13506.3 with 2pc and 13540.7 with with 4pc. I am human with enchanting and engineering as professions. It gets really shaky towards the very top end of gear because of crit capping issues. So depending on your profession might depend on if 2pc or 4pc is better; however, they are both extremely close so I would go after whichever you get first.
Regarding the second part of your post, not really sure what nerf you are talking about; but I am not behind mages, hunters or warriors. The only people that come close to rogues at the moment is warlocks (this is all based on the WoL reports from my guild, so this could change depending on guild), but by far... rogues are not behind. You should be topping meters.
