What kind of tanking rotations do you use for M'uru adds, assuming that you're tanking all 3 and the mage isn't going to be cc'd. What we do is kill the mage, I mark a beserker, that is killed after the mage, then the unmarked beserker is killed.
I tank ramp side and I've been starting with a white hit on the mage, then a swipe on all 3. Swipe again, mark one of the beserkers, maul it, swipe, mangle the mage, swipe, tab to the unmarked beserker, maul it, swipe, maul the mage, swipe, maul the marked add, swipe, mangle the unmarked add, swipe, etc.
I'm admittedly a bit undergeared for this and have been struggling to build enough threat with blade flurry rogues/sweeping strikes/whirlwinding warrior.
What I use for gear is:
T6 helm with 15 stam socket, 18 stam w/ stun resist meta, 18 stam / 20 resil enchant.
Brooch of Deftness
T6 shoulders with 15 stam sockets, 15 defense/10 dodge enchant
Slikk's cloak of placation with 12 agi.
T6 chest w/ 15 stam all sockets, +6 all stats enchant
Vindicator's dragonhide bracers with 15 stam socket, 12 stam enchant
T6 gloves w/ 15 stam socket, 15 agi enchant
Belt of natural power w/ 15 stam all sockets
T6 pants w/ 15 stam socket, 40 stam + 12 agi enchant
Treads of the Den mother w/ 12 stam enchant
Band of the Abyssal Lord
Ring of Stalwart protector
Guardian alchemist's stone (wtb shadowmoon insignia

)
Commendation of Kael'thas
Pillar of Ferocity / Idol of Terror
I have a 2nd T6 helm I can sub in, as well as T6 belt. I don't have the twins' staff or T6 bracers yet, or any offset Sunwell loot.
With this my unbuffed hp in bear is 20679, 31710 armor, 35% dodge, 2316 ap, 29.47% crit.
What kind of gear substitutions should I make that are available to me? Can I improve my tanking rotation?
Thanks.
