While Blizzard is hotfixing leveling, they should consider this proposal to fix a major problem of questing (outleveling):
Add an ***OPTIONAL*** NPC at each race's starting area that reduces all EXP gains by:
60% from level 1-60
40% from 61-100.
This would be just like the NPC that reduces all EXP gains by 100%.
Reward players who have kept this npc's buff from level 1-100 with a level 100 boost.
Net effects:
1. Players take twice as long to level
2. Players are given the same effective levels for their time investment
3. Players can enjoy the leveling content without fear of grey quests in every zone.
