So my guild killed Lei Shen tonight and I was wondering how in we would be able to devote alot of time to heroic progression, while also farming for gear to make it easier. We raid 3 nights a week, 2 and a half hours each night. We can get to Primordius usually in one night, and then I assume clear on the second. Which leaves us with one night of possible progression, which isn't ideal if the heroic content is hard.
How does a casual heroic guild kill heroic bosses and farm with only 7 and a half hours of raid time each week?
