That was my guild, and yes we tried using them. We don't use them anymore, and we haven't used them for a while. I personally never saw us use them (I joined the guild shortly before we killed her) but from what I heard it's just not worth it, and is actually easier without using them. We just time it now, and can get her down.
release the hounds!
one of the ner'zhul horde guilds gets endless flak because it's rumored (and they don't deny it) that their huhuran strategy involves farming dog whistles from SM :-P
but yeah, it seems excessive to me. isn't just resisting stuff easier? :)
And we DO get alot of flak from it, but we just ignore it.
