Ya I don't know why tho is out either. Ya they don't want 55s making easy runs thru ops but come on. Some of us want to run these at 55 so just let us!
Group of lvl 55 noobs won't make easy run through lvl 50 ops anyway. And skilled groups won't need it, so why not let the noobs L2P there? Sure they can but without GF it's harder to create group.
