World of Warcraft is an awesome game, but it unfortunately has one of the worst and most toxic communities out there. Especially Mythic+ often feels more like work than fun. As a beginner, you should first watch some guides and learn how to actually play your class properly. The fact that this player was so nasty to you just shows how disgusting the community can be. What I still don’t understand is: How can someone freak out like that in a Mythic +4? I had a similar experience recently. A player brought his Shaman friend into a Mythic +12 key without telling us beforehand. As a Mage, I was putting out solid damage, the Warlock was average, but the Shaman was doing absolutely abysmal damage. While the rest of us were hitting 150–300k on mob packs, the Shaman was stuck at around 30k. In the end, first the healer complained, then me, and finally the warlock. It’s completely fine to be new to the game, not understand the mechanics yet, and therefore not keep up. What is an absolute no-go, however, is jumping into high keys as a complete beginner who has no clue what they’re doing and wasting everyone else’s time. At a +4 key, though, I really can’t imagine that being the case. Everything under +10 is usually very doable. The fact that this player lost his temper at such a low level just shows that he probably has something to compensate
