when you play wow ,you may fell  more difficult at the beginning of this expansion's lifespan than they were at the beginning of Lich King. As new tiers of gear are released and new raids open up, Heroics will naturally become easier, but that provides little good reason for trivializing them now. This is true even if some groups -- particularly pick-up groups -- lack the patience, will, or teamwork necessary to succeed. We prefer that skill and character power provide the edge in Heroic dungeons, rather than supplying simple boss fights where mistakes are so easily forgivable. you may have you experience as you play ,you can communicate with your grop and help you .
