I don't like paying 90pts to kill my own guys for a rule that I should be getting a discount for in unit price. Plus adding that black orc in, would make the unit even more unwieldy in placement.
And really so far my offensive magic is not that great unless I get to fight monster infantry. Hand of gork is great, but no one is letting me cast it anymore, unless I get IF on it.
I think my more pressing concerns for the future are getting a magic weapon or 2 into my army because of all the ethereal vamp stuff about to come my way and getting a 2nd level on my lvl 1, to try and work things in favor of him having 'ere we go', since that spell is mostly useless in the hands of my lvl 4 as that max 12" range of the spell means that it's not really going to be there to help my savages most of the time when they need it.
Dropping a chariot and the great weapon on my savage big boss, gives me 54pts to take a cheap magic weapon on my savage big boss and raise my lvl 1 to lvl 2.
Then I roll for spells with my lvl 4 first, trade in ere we go if I roll for it and that should vastly increase the chances for my lvl 2 to have ere we go.
