I'm not even a mentor (trade doesnt count) and every time I've tried to help a new player, I've been chewed out or insulted or "you dont pay my sub" or "theyll learn in their own time stop telling them what to do" so I dont bother now, even if they're there cure 1 spamming. None of my business. Not sure what it is that makes newer players so touchy like that. I'd have loved pointers when I first started. I got to lv70 before anyone even told me that pulling w2w was the norm.

As for why people are this way to mentors, no idea. It is a thing tho I've noticed it a lot. For a community that prides itself on "niceness" and acceptance, they sure are vitriolic to mentors based on anecdotal past experiences.
