yeah gotta say the animation for this really sucks, I don't get how it's our only melee threat move, and they give it a casting animation.... they should make it use the 1h attack animation and then send out 3(4) hammers that hit the effected targets , not this wierd Exocast>hammer bounce rubbish we've got now.
although the libram does make it pretty good I'm just glad the proc on it is worth using, so I don't feel bad about keeping it just for the animation :P
