oh I got the bigger picture all right (hmm that is sounding like I'm mad at you, but I'm not, I'm just not sure how else to phrase it - I do appreciate your posts)
yes things can always be worse (and among other things, I'm aware how lucky I am to even have an opportunity to have this roof over my head, internet acess and both time and means to play video games as my leisure activity). yes, I now know what's going on with this particular dungeon and to avoid it in a future. I also had it confirmed to me yet again, that assholes will do a lot of mental gymnastics to both justify their jerk behavior AND try to shift any and all blame to the person they are being a jerk to. its not at all new to me, unfortunately, but I guess i haven't dealt with it recently (thank you quarantine, I guess), so my mental calluses are not as thick, so to speak. but they are starting to thicken again, so it wont' get to me that way next times wow jerks will be jerks.
I did also learn and interesting and yet ultimately useless to me fact. I had no idea you could finish regular callings via dungeons. I've always just did combo of quests and treasures. I only started doing the dungeons for that "dungeon or group wq" after how long one of those quests took me to finish first time around and I only ever queue up for specific dungeons on the quest list. I didn't do much of deliberate legendary farming either, and I certainly didn't look up what's best in slot for any class outside of druid (with my druid, after looking at my options, I decided to wait on crafting a legendary until I either level my own crafter alts, or crafting components are not as highly priced - I finished the quest with cheapest components I could find and dropped them off in my vanity guild bank for alts should they get to that point). so I had no idea that this type of farming was a thing. now I know.
