I tried returning to WoW (Classic) after a 10 year absence, thought I'd try tanking for a change instead of healing. Deadmines, what could go wrong?

Well, one mage managed to not only constantly draw agro from me, he also bumbled into the next group of mobs while the rest was still regaining mana again and again. Looted the box that starts that boss fight with a Tauren while the rest was not ready and wiping the party as a result. After that we all concluded that pressing on wasn't going to work. Fucking hell, never gotten such a toxic shit load of crap in my chat ever before, he sent me a book's worth of profanities all because "I sucked at tanking" according to him. Decided then and there that this was not the way how I wanted to spend my free time. When I quit WoW I already noticed that the social aspect was going down the drain, apparently it hasn't gotten any better during my absence.
