Rocked up in full Heart of Fear / Terrasse Heroic gear, fully optimised and ready to rock.
Got called a noob for turning up with not enough Ilvl by a full ToT Valor geared palladin. (I felt like I was back in the Gearscore days.)
Crushed him in healing done and RL kicked him.
Love flex, more control over who comes and who doesn't. No more PVP geared DK tanks that don't know their arse from their elbow.
Better than LFR, still not as good as Normal / Heroic.
