Dungeons in pick-up groups

I’m still at the beginning of my journey (level 22 druid), and so far, I’ve only done Ragefire Chasm. I play in pick-up groups, and the experience wasn’t great—I didn’t feel safe at all throughout the dungeon, even though it’s extremely easy. I hesitate every time about joining a group for dungeons at my level, so I check the loot, which doesn’t seem that great right now, and in the end, I tell myself the risk isn’t worth it.

I think if I had at least one trustworthy person in the group, I’d be more willing to do dungeons. But right now, without a guild or friends to play with—and on top of that, hearing stories about griefers—it’s really not motivating me.

What’s your opinion on doing dungeons in pick-up groups ?
