Go ahead and do it. Use the Forums and Open Raid to find people who are interested in doing so (not so hard) and go have fun. Why should others being able to skip content you enjoy doing stop you from ejoying it?
I've joined late in the expansion on a new account, and done exactly that. Cleared all raids by order using OpenRaid to find people, and I now have a full regular 10man group raiding weekly, 13/14 on SoO10n.

TL;DR:
You are not describing a better or even a good game (by today's standarts).
You are describing good memories of old and (now) bad mechanics. Good memories of gear mostly used to boost the player's epeen. Good memories of a time-intensive grindfest that rewarded players with virtual "cookies" instead of actual fun and enjoyable gameplay.
