Last night did Crota from the Shriekers to end on hard; then from the beginning to end on Hard; then VOG from Gorgons to end on hard, all in 2 and a half hours. If you have the right crew, now is a great time to jump into raiding; if the 5 other people know it all perfectly, you can easily get a full raid done in an hour. Or, as I did, just do one from a particular checkpoint.
