Contrast this to BC or Vanilla 5 mans (which everyone says Cata is a throw back to). Those 5 mans remained fairly hard all the way till the last patch (Heroic Shadow Labs anyone? Magister's Terrace?) I just find it funny how everyone said heroics were super serious and hard, and its only 10 days into the expansion and people are already facerolling.
*Note: Guild starts raids next week, and I'm sure those will be very challenging. But this post is aimed at everyone who says random heroics are impossible to heal. All my gear is from 5 mans or rep rewards, there is no reason you can't be as geared as me.
