What is says. Example: Copse of Treants. Without bonuses from pie or rebirth or AS, a bounty (not first kill) gives 40k-ish xp at level 78. Repeatable daily gives 5k. The discrepancy is ridiculous. They don't even have to be the same. Dailies could give 20k, even. Since a grind is required due to level-locked zones, at least even out the playing field a bit or increase xp from non-bounty kills. I'm not saying leveling is impossible, but it's certainly not enjoyable to be stuck 2 levels behind the next level-locked zone. That gap needs to be closed a bit.
Edit: that xp was with rested bonus. Just thought about that and wanted to add. Still quite a bit more than daily.
