Well I soloed Onyxia last night and was disappointed to find they had reduced her loot table to drop about 130g less the before. Previously She dropped about 160g + all the normal loot to vendor for a total of about 195-225g per kill. Not bad for an average of a 23min of work for my prot pally.
She dropped 51g
3 Epics
1 Tier token
Onyxia's 18slot bag
2 BOE lv45-50 Blue items
And 2 worthless green's
A total of less then 75g value I would say. Unless I can get a good price for the BOE drops.
