If you play long enough you realize that ilvl is temporary. Collections are forever.
There are a lot of ways to enjoy the game outside of the traditional pillars and competitive ladders. I’ve ksm’d/mythic raided and I can grind either out if I wanted the rewards enough.
That said the thing about mythic raiding is… ain’t nobody got time for that. They do have some juicy mounts/cosmetics that would look reeeally nice in my collections though.
Must not have leveled recently. You dont have to go through all the content from previous expansions. Heck you dont even have to do a full expansion to get to 60.
even if you were to level from 1 to 70/80 now, you would STILL be skipping content unless you just wanted to waste hours upon hours upon hours of doing all the quest lines for the lore of it. That is a players decision and nothing is stopping you from doing that, but I’d much rather just get the level needed to play with the people I actually pay to play with.
