Warcraft is a game about upgrading gear. Always has been, always will be. I could see not putting a huge effort into getting the maximum gear possible when an expansion is near, but "pointless" is too strong of a word IMO. I have fun raiding, I have fun tweaking macros, gear, gems/enchants, to see bosses go down faster, trying out hardmodes, etc. Gear is secondary.

If you want to play a game where your gear lasts, wow is not that game.
