@Tyranno regarding the Lust chosen, it depends on what you want their role to be.
Halberds are always good on them but ahw are great against elves as they quite often hit first or simultaneously (I 6!). I tend to run ahw on my lust chosen but it also depends on what the army needs otherwise ofcourse.
The only Chosen I have so far are the massive Nurgle guys.
Thing is with no Army List I do not have a role for them yet.
I already have un-Marked Warriors with Halberds, Un-Marked with Shields, Khorne with Halberd, Nurgle with Halberds, Tzeentch with Shields. So quite a variety at my disposal, I was hoping Lust made one option obviously better, guess not :P.
