Improve player experience

Hey guys I wanna try be more helpful in WoW and was looking for examples of really positive experiences you’ve had in WoW so I can find out what kind of things I could spend a bit of time doing each week to make a small difference in the community. Something Ive been thinking of doing is help people get started with Mythic+ dungeons as I’ve seen a few posts on social media where people are anxious about joining mythic+ groups because they are worried about making mistakes but I’m not sure how I would go about helping them with this.
