In all seriousness, if you do think that people doing things only to get gear is a wrong approach, your approach to the game is wrong. It's one of the reasons I hate people trying to sell their opinion as facts.
I, and many others, do get their joy in the game, at least a huge part of it, from items. Who are you to tell me, or us for that matter, that is wrong? I raid to get gear, I do m+ to get gear, I pvp to get gear. What a pity my wrongful approach is actually fun for me.
Also I kind of agree, not completely though. M+ was designed as an alternative to raiding wasn't it? That's not the case though. If you wanna be top of the pops gear-wise you have to do all. You'll need weapons from mythic raiding, which are 445 and can forge to 455(weapons can only warforge, never titanforge => 440 from m+, 450 from weekly chest is max(if you're insanely lucky that is)). Trinkets from raid are usually among the best too. And for some azerite pieces might be better than what can be gotten via titan residuum. That's it though and most of that can be had from the first 3 mythic bosses, which any crappy random group can do. The rest can easily and easier be filled by benthic(when raiding), m+ gear and your professions.
