Help with rings please

Hi:

I currently have http://www.wowhead.com/?item=37784 and http://www.wowhead.com/?item=42643

And I just got http://www.wowhead.com/?item=40426

Any Advice on to which 2 to keep? I can sell the new one if it doesn't make much of a difference.

Thanks

I like what you have equipped.

Honestly Signet of the Accord is good if you don't have epic rings yet but both Keystone and Titanium Earthguard are very strong pieces and better than Signet.

so I should sell it?

Yes, with you defense trinket, you don't even have to be concerned with the lack of defense on the keystone ring.
