Deathscreamer

That name brings to mind the original Tyranid Carnifex, until I then recall that it was instead called a 'Screamer-Killer'. Anyways...

So, I've been tweaking around my Purge/Blood Eagles list and thought of Swapping my HQ's around. Normally I run Ivan as a sorcerer, and Exedore (doubt that name will work, as I still call him 'George' then correct myself) as a Lord. After the repaint and name change, I thought to move Exedore to a sorcerer, omitting a lord choice all together. I know people swear by demon princes, but I've gunned down enough of those with lasguns to ignore the supposed 'only viable HQ choice' (and I also use the DP model as a greater demon which dies just the same, but only for about half the points + a champion which is much cheaper).

Now, usually Ivan just has his trusty 'doom bolter' and no marks, but I was reading through the Demon weapons entries and happened on the Tzeentch 'Deathscreamer' which when given to a lord is far better than a sorcerer with doom bolter. It requires a mark of Tzeentch, but that's both cheap & useful, so no issue there. However the Deathscreamer rules, when combined with the Demon weapon rules seem broken if taken literally.

Demon weapons:
•Are a power weapon
•Require 2 hands
•Grant the wielder an extra D6 attacks (unless you roll a '1', in which case you take an automatic wound with no armor save and make no attacks)
•and have the additional benefit as detailed per Chaos mark.

Those essentially being:
• Undivided: +1 strength
• Khorne: ungodly potential number of attacks!
• Nurgle: Poisoned 4+
• Slaanesh: instant death regardless of toughness (I wonder why I don't see this one more?)
• Tzeentch: 'can' (will come back to that word) make a shooting attack @ ST:4, AP:3 Assault D6, 24" range. If you roll a '1', you get no shots & instead take an auto wound with no armor save.

Now, it says 'can' make a shooting attack, but nothing in there states that it replaces the HTH attacks, like its an either/or kind of thing. Personally I think that the shooting profile replaces the HTH profile, and you end up with a lord that's a potential shooting monster, yet only has 3 savable attacks in HTH (which is presumably why I've never seen this piece of wargear on the table top). BUT 'rules as written' basically says you get both (which just sounds broken), while 'rules as intended' (I think and is how I will play it till proven otherwise) is that the shooting profile replaces the HTH characteristics.

I checked the FAQ, but it mainly focused on Typhus, and the stupid 'lash' issues. I didn't see any mention of any other demon weapons at all. So I'll ask all of you out there wandering through the blogosphere, which do you think it is?
