The quest I was speaking about was with fumble the troll, where the only way to complete it is via dialogue, killing him doesn't work for the quest.
I agree that the numbers can be played with particularly for quests like Victoria's but the fundamental aspect that the quest offers you 4 different resolutions depending on your playstyle and that should be encouraged.
FYI the PDF you linked is for the classic edition and not the enhanced edition but your numbers are probably still fine.
You also have simple quests like the one to kill or spare the charmed orc that nets the same amount of XP.
At the end of the day sometimes the quests will make sense to give more XP. As long as the times when a non combat solution would be equally viable or make more sense and that it is rewarded, the game should have something for everyone.
