Traditional wow always had raiding and end game content that was intended to be challenging for the more hardcore and serious players that want to push their ability.
Not sure what you’re complaining about, but I for one am sick of hearing from you whiny toxic casuals about how challenging content shouldn’t be in the game and trying to portay it in a negative light and trying to make the entire game cater to you.
99% of the game caters to you, but mythic+ and mythic raiding exists and I’m guessing the real problem here is the idea of doing harder content to you in a group environment makes you feel insecure and bring out your petty, jealous side.
You’re like crabs in a bucket, trying to claw everyone back down to your level because seeing other players with higher ilvl gear or achieving things in game that you can’t makes you feel small or inadequate and you don’t like that.
I know this because I have talked to people who have a negative attitude towards raiding and end-game content and in the end all the hate always boils down to the affected person having a form of “raid anxiety”, or a delusional fear that the end game community will tease or reject them, so as a self-defense mechanism you reject them first and attack them because that is how you imagine they would treat you, although this isn’t the case in any reality and is only a made up head canon from your pettiness and insecurities.
This entire “problem” can literally be solved by simply staying in your lane and minding your own business instead of obsessing over what other players or community’s are doing, there will always be “hardcore” players, and there will always be “casual” players.
It’s been a long time since I’ve seen any “hardcore” players be rude to casuals, but you casuals can be really nasty and toxic alot of the times and you think your “casual” status gives you a sought of immunity to criticism because you believe “casuals can’t be toxic!!!” but this isn’t true, there are plenty of wonderful, kind players at the highest level of the game and there are some super nasty petty, jealous casuals that constantly compare themselves to everyone else in the game and lash out at them for having the audacity of taking the game seriously, it’s pathetic to me.
Again, stay in your own lane, focus on enjoying yourself and all these “problems” you are having will cease to exist.
