Welcome to my Hand of Freedom list!
This list will grow as our content and my personal experience grows. Please feel free to e-mail me... enlynn-at-hotmail-dot-com or leave a comment over at the Freedomization blog page here if I've missed anything!
FIVE MANS
Stonecore
Blackrock Caverns
A few here you would think could be cleansed by Freedom, but don't. Boo: Shackles, Shadow Prison, and Statis Strike. With names like these, HoF should totally work!
Vortex Pinnacle
stacking poison debuff used by Empyrean Assassins (rogue elemental trash).
Asaad does an ability every 15 or so seconds called Static Cling (you can also jump at the end of Static's cast, but we can safely assume that HoF will still come in handy).
Grim Batol
Twlight Drakes do an ability called Hooked Net that does not show up as dispellable, but your melee will love it if you free them.
Erudax does an ability called Binding Shadows. Sadly, HoF does not remove the debuff (though it will let you move, the ticking damage debuff must be removed via traditional means. Better yet, this can be avoided!)
Halls of Origination
Earthrager Ptah
Dustbone Tormentor, Trash before the Sand-Marrowgar boss does Curse of Exhaustion. Freedom!
Ammunae
The Lifewarden Nymphs before this boss do an effect called Entangling Shot.
Ammunae himself does a debuff called Wither. Your DPS friends will love you if you remove this buff sooner rather than later (this fight is long enough as it is!)
Setesh
The Void Seekers before this boss can do Anti-Magic Prison makes the target immune to receiving heals. Hand of Freedom works, though it doesn't show up as a magic debuff to be dispelled.
RAIDS - TIER 11
CONCLAVE
Conclave of the Four Winds. I was disappointed when I tried using HoF for frost trap. No debuffing for us, here, at least on the Frost platform.
Alakir. (Info incoming, my raid group has yet to make any serious attempts on this boss).
BASTION OF TWILIGHT
Magmaw. No debuffs here that I'm aware of.
