Warrior - Problem with Garuda NM

[Giantbane]

Hi everyone.
Today I've started doing tries to Garuda NM.

First I did so as level 44 with duty equipment, and we decided to leave since we couldn't reach even 10%.

Now 46 and 45 job quest done I thought about giving it a try and the first one went almost perfect but we wiped at 3%.
However, after that one, I lost the aggro (or enmity) surprisingly and I didn't know why.

I always start using Tomahawk, then Heavy Swing -> Skull Sunder -> Butcher's Block.

After that I use Heavy Swing -> Maim -> Storm's Path and Inner Beast whenever I can between rotations.

I've never had any problem with aggro but this time it was impossible to have it stable.

I told my party members to wait until I did the first rotation to start attacking or healing but, I don't know why, after that first rotation Garuda just goes rampage attacking everyone and moving from here to there.

Am I doing something wrong?

Personally I would start with
Butcher Combo
Vengence
Storm Combo
then hit Unchained->Berserk->Inner Release (don't just hit them all at once, work them into the combos so your combo isn't interrupted)

and continue with:

Butcher Combo
Butcher Combo
Storm Combo

for the rest of the fight, and you shouldn't have any trouble with agro.

And I would save Inner Beast for when you need healing right now, and not just use it on cooldown. It doesn't generate enough agro to be worth stopping your normal rotation for it, and when you drop wrath stacks, you're losing 10% crit which also helps you generate more agro.
