The Spirit Realm

DoN is another path you could take. I haven't been able to get any RSS groups yet (just made 70 last night) so have been grinding out Creater missions. A bunch of the buyable armor from that would be upgrades as well.

There are also a couple random drops in the missions that would improve you as well.

But overall it seems you are better geared then I am, so I'll shut up now.

Earring of Oppression should be an easy aquisition just by grouping for a night in WoS. Most people seem to already have one, and there aren't many groups out there anymore.
