You need rhinos for the infantry - at minimum the doom siren ones. Not sure why the lclaw is on a shooty unit and not in the assault one
That's a fair point. There is no logic involved here; the fact is I have a non-Doom Siren equipped model with a really cool old lightning claw that I'm reluctant to butcher at this stage and for philosophical reasons I cleave to the idea of
WYSIWYG. You've made me wonder whether to remove a champion, though, and make a 10-man squad of some sort. Not sure what yet...
An ML1 marked sorceror isn't going to do a whole lot..
As for this dude, I've been under the impression that some psychic presence is necessary in 7th ed. But maybe not? And if this is going to be a waste of points I might start considering those Rhinos (well, I've got one Rhino). Points-wise, if I'm going to increase his power I'm going to have to start cutting infantry, which here is already in short supply.
Thanks for your feedback.

Much food for thought.
Automatically Appended Next Post: So I've decided to exchange the close-combat Noise Marines for close-combat Chosen with Mark of Slaanesh instead (for waaaay more attacks and at the same Initiative value), and stuck the Lightning Claw Champ in there. I've dropped both Doom Sirens, which feels wrong somehow, but I don't envisage my Sonic Weapons dudes getting close enough to make use of them. Now I've got 20 points left and I'm wondering whether to cull a chosen (20 points with Mark) to fund an additional mastery level for the Sorcerer. If so, that'll leave me with 15 points. Maybe I cull 2 chosen and buy a Rhino as well...
I can't decide!!!
