All of the issues with the rogue class and the talent review are nicely summarized in this link (the Rogue Talent Primer link I posted elsewhere):

Synopsis:
Yes, it's great that we can spec for 1v1 burst damage, but only successfully every 10 minutes, and all of the battlegrounds and most world PVP besides ganking is Many-v-Many combat, in which case we rogues are singled out for immediate stomping. We're NOT the top of the PvE charts against DPS Warriors or Mages/Warlocks, yet it's our only usefulness in raids.
Again, way more detail in the forum link. But we're by no means a "polished" class.
