The price did not drop because of the expansion. The price is driven by divine logs, which is a drop from ANNM, which made them more readily available. Before they were only available from ks99's, sky, and a few HNMs.
Shura Kabuto +1/NQ will be beaten easy by Champion's Galea from new expansion, if you can get to hold Champion’s Galea by any chance…
Champion’s Galea base status: DEF:24 HP+15 "Counter"+3 Agument: STR+4 WS Acc+15 and STR+2 Haste+2% Total status: STR+6 WS Acc+15 Haste+2% and DEF:24 HP+15 "Counter"+3 (Comment Score: -8, keep on going with the minus ;))
As you can see the price for this cursed item dropped from 500k to 250k and price continue to decrease
