This is just anecdotal, but I've yet to see any vitriol thrown my way over mentor status. I have seen occasional cranky/snobby/edgy players, but I don't let them get to me. Probably something I learned to deal with when I started leveling tank jobs for the first time when HW launched.
Now I don't go out of my way to offer unsolicited advice unless someone is clearly struggling with something I'm familiar with or unless someone asks, but I always say hi at the beginning, congratulate everyone and wish them a safe journey at the end, and maybe remark on close calls and good saves if I see them.
If someone gets cranky about it, I'll pipe down, but only for that run.![]()
