Yet that is the game.
Just like if you want to play the RTS campaign, you need to learn the special skill of managing base building and producing units, harvesting resources, and managing troops. It isn't going to be a Hero-focused RPG or MOBA. If you want the latter, best to find a different game suited for your needs.
Sounds like a single player RPG would be better for you, honestly. Or a more casual oriented MMO. I used to play Phantasy Star Online 2, and it is a SUUPER relaxed mmo that has varying ranges of difficulty. All end game content has a super casual mode option and there was literally no toxicity when I played. And if you want to solo raid bosses, you have the option to do content tuned to solo progression (but it is actually harder than group content since group has unlimited player revives, while you only get one chance in solo)
So I'd prolly suggest trying more games out rather than holding on to WoW as though it will become something it was never going to be. But I totally get why you'd want to stay too, since there is sentiment to the character you built and the world you want to be in.
