Well in my progression to 80, been about a week now. I found no trinkets that would have been an upgrade for tanking. Still using Figurine of the Colussus and Darkmoon Card Vengeance.
Well like most WOW players, Tuesday morning sucks, specially if you do not work at this time. SO i do what most do I search for items. Well I came across 2 trinkets that look pretty nice, wanted to see opinions or maybe better ones.
Seal of the Pantheon http://www.wowarmory.com/item-info.xml?i=36993
Essence of Gossamer http://www.wowarmory.com/item-info.xml?i=37220
Neither are Epic, but I like lots of stamina. And the 2nd is over 1k extra alone.
