Fading works well for pulling. Lets say you are in BoT, Kael, or maybe Sebelis and there is a mob up that you want to pull all alone. Pacify is nice, but some mobs cant be pacified. Or maybe paci gets an aggro resist.
BAM! 2 yellow and one red Mob inc to your group.
Without fading memories, you have 2 choices.
Die in place and /cosent a group member
bring em all to group and hope like hell you can CC your mess.
With fading memories however, your options increase a lot.
Fade and try to paci again.
Mezz the 2 adds, bring the third to camp, then fade. The mezzed mobs have no aggro anymore, they wander back to camp.
Use the gate song and send the adds back home, then fade, bringing the mob you want all alone.
Fade and try to split the pull monk style.
Fading also works well for Rampaging mobs. Bards tend to creep up the aggro list slowly but persistantly. Whenever I am raiding or fighting a rampaging mob, I usually get aggro once or twice. Before fade, it was back away from the mob, break out song of dawn, pulse that sucker 5 or 6 times, then wade back in. With fade its just FADE, no break, I go to the bottom of the aggro pile again. Lets me twist what I need to twist nonstop and still melee.
Fade also helps a lot to get you into or out of tough to reach places. Went LD deep in SSRA somewhere and couldnt get back on till your raid moved? Fading can help you get out alive if you dont have any way to gate.
Fade also has it uses in areas where spawns are contested. Some monk just pull your mid south named to Deep south? Run through the whole south, taking all the giants behind you. when you get near that monk's group, fade and walk away, /emote a laugh while his party dies.
Ok, all except that last one are GOOD uses for fade ;o)
