Right now my guild is just getting into downing 10-man raid content. We've been hampered by some less-than-ideal group makeups (2 hunters and 3 druids ftl ). We're trying to expand to open up another 10-man team by picking up a couple of mages, holy pallies or shaman. Once we do that and can split up our hunters and druids, our progression should kick into high gear.
I'm about 7k from exalted with Therazane, and plan to unlock the epic shoulder enchants in the next day or two.
I've got all the heroic tanking trinkets but I haven't quite decided which ones to use. I've settled on Tia's for one slot, but for the bottom one I keep waffling between the alchemist stone and stam trinket from Stonecore.
If anybody has any critiques or suggestions about my optimization, gemming or spec, I'd be thrilled to hear it.
From what I see you are in a pretty good place. Trinkets as you mentioned are not necessary plug and go.... make sure you have a collection of them since some fights you are going to want to go with two stamina ones. And as long as you are not having issues with threat your Hit/Exp are fine.... I run with very low Hit/EXP and have no issues with threat.
