The thing is, in my opinion Classic is an endurance, not a sprint. So it’s about consistency more than anything else. And since we have nothing but time with Classic it’s not if you experience all the content, but when you experience all the content.
As it stand I arguably have more time now than I did when I was 14 years old in Vanilla. I have an excellent career, a fiance, a house, and no desire to have kids with an intention of raiding in Classic.
Everyone is going to be on different paths. Overtime everyone will contribute in some capacity that will hopefully be an amazing re-release of one of the greatest MMORPG’s of all time. Will it be for everyone that played back then? No. But it will bring back a good chunk of old and new players who will fall in love with the game once more.
