I'm not asking for new stuff to be added to old loot, just to bring it into line with current play.
Two examples:
Just completed the Threnal series, and took the Kundarak Trooper's Shield for the Heavy Fort augment - but the augment slot is still of the old variety and so you have to use the legacy augment remover to extract it. If you wanted to actually use the shield with the new augment system, you'd have to remove the hvy fort augment, log out, back in, then place a new augment in the slot (maybe even the same Hvy Fort augment).
The old named items such as Seraphim (L11) and Epic Seraphim (L27) are both still at basic Hallowed and Sacred, while random loot outstrips them at L7 or 8 with Hallowed 3 or Sacred 4 (that type of thing)
