Beside the Urn and the mythical goldbar.
The Auberon & Omega Anima drop rate is pretty much the same as leeching the non-HL 30 man-raid Counterpart (considering how 30 man raid, have lesser time spent and how it is spammable by leeching).
In addition, leeching in HL is rude (which is why I don't leech in HL, and therefore time consuming), but leeching is 30 man raid is normal.
