Some folks don’t have all the heirlooms.
Back in the day, I did have every heirloom from Wrath because I ran dungeons like crazy. But this time around, they had so many difficulties and so many people that wanted absurd requisites, I didn’t get to spam dungeons this time around. I only have the helm/cloak atm.
There’s just too much “If you don’t do x amount of dps, you gettin kicked” where as back then, it was like “Dude don’t worry, we gotchu” it was pretty chill.
