How are you defining relevant? Anything that helps a player qualify for current content (Slowcloak/Sastasha/Qarn have an i80 requirement; ST has a i70) is still relevant as far as I'm concerned. It may not be relevant for all players as gear, but why should it be?
No, we'd just point out that older MMOs were grindy too, and perhaps you should wipe the rose color off of your glasses.
