The questions you have about Thorim have been answered already in this thread. I suggest you look harder next time.
I came on here to ask a question about Thorim hard mode, and ended up with another one.
Why does moving the boss cause any problems at all for the ranged? Why are some people advocating ANYONE take soak the lightning cone, whether it be tanks or melee DPS? Taking 20k+ spike damage is something you usually try to avoid.
And my original question; I've seen some people using druids with PvP gear do it - my guilds normal tanks are a warrior/DK, as I've been DPSing since the patch. My tank gear is limited to BiS naxx pieces (Except for the Darkmoon Card, which I've still not managed to save up for). I do however have several pieces of PvP gear, all from last season. I have Deadly gladiators Belt, Boots, Bracers, Neck, Cloak, Chest, Gloves and Hateful legs/Helm. I could easily regem all for stamina.
My alternatives in case I have too much PvP gear is 5/5 Valorous T7, Boundless Ambition/Heritage, Cloak of Shadowed Sun, Thrusting Bands, Belt of the Tortured, and Footwraps of Vile Deceit.
How much resilience is recommended to go with for tanking Thorims hard mode? And with the druid tank in full resil, I assume the strat would be to eat all the UBS's, start popping cooldowns around 7-8 stacks, and then when/if you die, have your 2nd (and possibly 3rd, if we decide to use one) tank take it and pop their cooldowns, and hopefully the DPS can get him down around 12-14 stacks?
