The Abonimation Known as WTFWHM

[Alistaire]

Oh I hate fluid aura, I whm and I have never seen a legitimate reason to use that skill.

Killshots. Also moments where tank's lost control of something and you're in danger. Also mobs that are immune to the knockback. Also mobs that are up against a wall, especially when you have no mnk/drg where what little knockback won't affect your dps. Also mobs that need to be pushed/brought somewhere (turtle in the guildhest). Also any 2nd target that will effectively have their move nullified when nobody else can do it (like the maidens with the terror move in haukke).

And the wtftank list continues:

-Tanks not having Shield Oath/Defiance on while tanking

For most bosses in dungeons it's more of a wtf moment if they keep those on.
