It would be a good idea if the developers decided that everyone has access to quest givers, like with global resources.
All the issues related to quest givers are also well-documented.
I also understand those who want to be able to fence off quest givers and build roads to them.
Therefore, I'm in favor of quest givers being able to be destroyed, but not with impunity. So that the perpetrator could be tracked, perhaps with a debuff like for killing a player. It would also be harder to do than it is now. My suggestion was to make them hard, so that only a player with a certain high Strength stat could cut them down, but I also like the idea of a duration. Ideally, I'd add both, so that even with Strength, the chopping process lasts a long time. Perhaps until death. From the person who came to turn in the quest.
