As someone who learned all the mechanics by playing a DPS, playing a tank is a cakewalk once you know the limits of your class and your party.
My TW experience was just… Waddle forward on slow DK legs, use a lot of cooldowns and slap things. If I had CDs, I’d pull big, if I didn’t, I would pull small. Places like Mana Tombs had some pulls I did small simply because stuns without IBF would be sad times for all. By the end, one of the DPS that was with me for all five runs whispered me with a thanks.
LFR works pretty much the same way and hoping the tank knows to taunt on Smolderon.
