Some of us quested these spells over 7 years ago before we knew that eventually the level cap would increase beyond 75. Now that we can sub some of these mages and utilize these spells we find that they're very rare or sell for million on AH. There is a severe shortage of these spells because only one of these spell scrolls can exist per player. Any avenue created to attain these spells besides the scroll would be an infinite improvement. Even if its a low drop rate from Caskets or WoE it would generate more scrolls in existence. The only way currently to make new scrolls is for new players to do the quest and decide they don't want it and AH it OR to create a new character to level up and quest it themselves.
