They should make the weekly the full run so I agree they changed EC to a full run it used to be at the tanks for the weekly. But I can see issues for pugs doing brontes/council with the half wits we have on the harbinger always failing on those 2.
Indeed, people need to be careful what they wish for. With the shear amount of bads around, you'll be hard up to finish your weekly's often if it were changed to final boss.
Maybe more incentives to finish the op other than a couple more comms?
