Hey everyone, new to posting, but frequent reader here.
My guild just killed Kalecgos tonight, and we're excited to down Brutallus as well. I was reading the Brutallus discussion in this thread, and a druid or two mentioned they were considering using
[Brooch of Deftness] instead of
[Pendant of Titans] for Brutallus. I've considered this as well, but am having trouble reaching crit immunity. This is what I'm thinking about for my gear setup for Brutallus:
[Thunderheart Cover] (+15 Stam, +18 Stam/5% Stun Resist gems), (18 Stam/20 Resilience enchant)
[Brooch of Deftness]
[Thunderheart Pauldrons] (+15 Stam x 2 gems), (10 Dodge, 15 Defense enchant)
[Slikk's Cloak of Placation] (+12 Agility enchant)
[Thunderheart Chestguard] (+15 Stam x 3 gems), (15 Resilience enchant)
[Band of the Swift Paw] (+15 Stam gem), (+12 Stamina enchant)
[Thunderheart Gauntlets] (+15 Stam gem), (+12 Agility enchant)
[Belt of Natural Power] (+8 Agility, +4 Agility/+6 Stamina gems)
[Thunderheart Leggings] (+15 Stam gem)
[Treads of the Den Mother] (+12 Stamina enchant)
[Ring of Unyielding Force]
[Violet Signet of the Great Protector]
[Badge of Tenacity]
[Moroes' Lucky Pocket Watch]
[Pillar of Ferocity] (+35 Agilty enchant)
[Idol of Terror]
With this gear setup, and a Flask of Fortification, I'm 21 Defense Rating/14 Resilience off from crit immunity.
I am thinking my best bet is to swap out
[Moroes' Lucky Pocket Watch] with
[Shadowmoon Insignia]? Another option I suppose would be to not use the Brooch at all; and instead just use the
[Pendant of Titans], still.
I would appreciate feedback on which would theoretically be a worse downgrade in terms of tanking Brutallus. We killed Illidan about 6 weeks ago, so our DPS might not be high enough to kill Brutallus just yet - but I'd like to make sure that the tanking is set so it's one less thing our guild has to learn for the fight.

Thanks to any responses.
