What about YOU being respectful of OTHER people, and their time and work and effort? Respect goes both ways.
This is demonstrably untrue. You’ve received plenty of helpful comments. Just because you don’t like the advice and it isn’t what you want to hear doesn’t make it unhelpful. You’re making a conscious decision to decline the help you’re getting. That’s not the same as not getting help.
I can understand that you feel sad and frustrated that you can’t play the way you want, that you’re going to have to put more work and more effort into getting where you want and doing the content that you want in game, but that’s the reality with many things in games and in life. Whether it’s worth it or not is a choice only you can make.
That’s valid advice for a solo player, or someone playing casually with friends who don’t care, but OP is trying to do high end competitive group content, mythic+ dungeons, which means other people are depending on him to have the proper tools and skills.
Then accept the fact that you’ll have trouble in group content and bring others down with you because you refuse to do something so simple and helpful to yourself and other people.
