So here's my situation...
My druid alt's trinkets are reign of the dead and sundial of the exiled.
My chances of getting a broodmother or dragon queen are slim to none since several of our main raiders still need them and i'd be obligated to pass to help progression, after losing several of each... i've given up on them.
Last night i picked up Fetish of Volatile power heroic from toc 10...
I figure i'll time the fetish nearing the end of wrath eclipse, that way the stacks will max out quick and it will be just in time to utilize the bonus 512 haste on starfire eclipse. I can also time starfall (faster stacking) with the trinket, not to mention the pillar of flame from reign of the dead also contributes to stacking.
Personally i think fetish is better, what does the boomkin community think?
