I thought I did, but I didn't. I quit classic a month or two ago. Was in a top guild on our server, did 30m BWL clears, great players, etc. Game just isn't fun anymore. Everything is trivial. Everything will be trivial - no, AQ and even ooo scary Naxx won't be hard. World buff and speedrun meta is so laughably boring and pointless to me - I just don't get off to that kind of thing. No one runs dungeons anymore and it's all about getting boosted. Having a mage just prints gold - economy is probably fucked going forward. PVP got boring after a while, but was admittedly a blast for the earlier phases. Rank grind is an awful system that doesn't reward skill, but rather just time and commitment. I've primarily been a pvper since actual 2004 vanilla, and man, I remember not missing vanilla pvp once TBC and arena launched and I still feel the same (however, I do wish there was no flying, because that really did fuck up what wpvp you did get into).
tldr: Classic isn't classic. People play games differently now. Game isn't hard and is very zzz.
