I saw a comment on the pally icy veins forum that made me think of you:
Currently the bubble taunt on oregorger can bug out and randomly one shot a ranged player. it works maybe 90% of the time but every now and then it will murder a random ranged.
No details about that bug, but you're apparently not the only one who went splat after a pally taunt. Worked great last night, but last week...
Hahahahahahahahahaha!
That's amazing. Sorta glad that I wasn't imagining it. :)
For Science!
