- a somewhat hardcore progression oriented guild should be aiming for killing all normal bosses in at max three IDs, then heroic in another max 6 weeks (roughly two new heroic bosses each week). so after two month roughly (9 weeks), content should be cleared.
- a normal casual guild (like mine) will be aiming for clearing normal content in 2-3 month, and going for heroic progress "as much as possible" until the next raid will be released.
