That's not true at all, you're just cherry picking weapons. There's still a lot of demand for Tear, Prestor's, DFT, Ashje, LgGem, RejGem etc. and they will remain hotly contested. That's not even considering the people who will take BWL upgrades while waiting on their AQ40 upgrades.
It also doesn't consider at all that we've been sitting in BWL for 4 months already, which is more than enough time to provide value to any items acquired. Yes, a 6 month wait was what happened in Vanilla - but guess what, it was too long back then as well. That's exacerbated by the speed we consume content these days.
