Considering the 2.x relics remained best in slot until level 59, and they were good for at least six months to a year prior to that, I think the argument of "it'll only be good for two months" is kind of flat.

XI relics were good for years, but they also took years. XIV's 2.x relics are good for months, maybe up to a year, once they're finished, and after all the nerfs they certainly didn't take more than a few weeks to get.

Let's see what more they add to the anima questline before we discount the possibility that they'll be 5-10 iLvls above everything else by the time 3.x era ends.
