Being able to double or triple the instance reset timer (say, from one to three weeks) for a raid leader would solve that problem, without that much of an influence over the higher end guilds. And I'm not afraid to say that this benefits those who are willing to put efforts into raiding, but just miss the little something that allow them to beat a raid dungeon within a single night.

Here would be the raid instance difficulty:
0: heroic - 1 week reset, and the instance becomes locked out after 24 hours. Also toggles "mount/vanity loot" on along with quests for special titles/rewards
1: hard - 1 week reset
2: "normal" - 2 weeks reset
3: "easy" - 3 weeks reset

People would be saved for one week, except the raid leader who would be able to invite people back to his instance for as long as 3 weeks.
Progression through content would be less effort-consuming, at the cost of less loot overall (due to the instance not resetting every week), rather than nerfed battles.
