The day I hit level 70 on my girls we equiped all the Seer's Mail gear and cleared 3 level 70 instances with mixed success (the first being Shadow Labrynth). Basically I just stand in 1 place and have the shit kicked out of me until I die - or more preferably - they die. To be honest I've not even attempted the kiting method (mental note, attempt kiting method).

My technic is: Drop 3/4 totems (Wrath of Air, Healing, Mana, Totem of Wrath). Pull the first mob and hope it dies before it has a chance to beat on me. After it dies drop all Stone Claw Totems, depending on the mobs I might backup, but usually I just stand my ground. From here on out its just a matter of DPS them down asap. My preference is to take out Melee mobs first and casters last I found it works better for me. If it all turns to poo I would rather die than use an Earth Elemental, prefering to leave them all to the boss(es).

At one point I was running into a few issues with either lacking DPS or HP. After swapping around a few enchants and equiping some Stam gems (where previously I had +crit gems) I managed to move past it.

My main has higher stam, as I try to tank with her. Stam gems, stam on shield etc. After hitting exalted with Sha'tar (last night woot) I've got the enchant to add threat to gloves, this had made a bit of a difference and she appears to hold the mobs a bit longer.

When I was running Ramparts I absolutely dreaded the Beast Master and the 2 Destroyers, if I was gonig to wipe it was on that pull! I had more trouble on that pull than the bosses. I thought myself lucky if I only lost 1 or 2 girls during that fight
