Looks like the June 6 update should see some very nice changes

[dev1015] Abyssea Update Scheduled for June 6
* Sturdy pyxides in Abyssea areas will appear in significantly greater quantities.
* Players will be given the option to manually destroy any sturdy pyxis.
*When exercising this option, the destroying player will receive a cruor reward proportional to the rank of the pyxis.
