Think he might be referring to the fact that they give out certain item types, the latest loot they give out is AoS weapons. They don't give SE/ML Loot.
I personally find this a good thing, for often times i'm looking for good "old" loot types, like Maces and Kats, or just some Platemail with nice mods, but have to dig through tons of "Expansion" types of loot. With Dark Wisps, you have loot intensity comparative to that of Swoops, and the "Loot Pool" isn't "polluted" with ML Loot. Just yesterday i got a Halberd with 42% Fireball/11% HCI/30% SSI/32% Dam Inc, and mixed Elemental Damage types. I was on my Tamer/Mage with 2011 Luck when i got it. 1461 Luck from suit, +550 Luck from 10th Anniversary Sculpture.
If you're looking for a good "legacy" wep type, like a Kryss, Kat, Mace, etc, and you can't afford a Runic Hammer, the best thing to do right now is to hunt Dark Wisps for it. Before the new Event, i used to hunt Succubi/Balrons for "Legacy" loot, and even with extremely high luck, rarely found any good pieces.
