Warlock Spec's, what do you like and dislike?

Good day All!

Just wanted to ask about it, I see some of you have taken Haunt in Affliction, but have not heard much from those of you who have gone Demon tree at all, I have 2 locks that I tribox with my Spriest and was wondering about this, I like the whole Haunt thing and I actually spec'd one Affliction one Demo tree all the way to metamorphosis. I really don't get the whole 51 point for Demo, its cool graphic wise and all but will it work for multiboxing? I see it as a last ditch effort to tank something at the end if you get pets killed or something but what else? I have not played it a whole lot since patch came out so dont have a big opinion of it, for those that have multiboxed it what do you all think, well for any of the tree's what do you like and dislike and is the 51 point worth it?

Thanks

Haunt looks absolutely delicious for pvp, but thats about all I have to comment as I do not have a warlock team high enough to try it yet!

I've always wanted to try destro, but never have. Affliction is great, but not needed for regular mobs if you have more then 3 locks; Demo is strong for instances, though.

My main is a Warlock. I've specced affliction, demo, and destruction in the past.

I'm demo all the way as a boxer. Its hard to beat the low-micro requirements of the felguard. While I haven't played much in 3.0 it looks like the Felguard's been buffed.

So, trash mobs: send in pet, spam shadow bolt, my pally holding aggro. For boss mobs, add corruption/CoA/CoE. Seems pretty low maintenance.

A lot of the new talents (all classes) "feel" micro intensive. To me, that's anti-boxer. ymmv
