Now before we begin, I'd like to make it clear that I can only appreciate ogres from theory. I say this cause I have never played, nor seen played an OK army, that said I feel I should ask this question as I'm thinking of picking up some OK myself.
Gnoblars seem like a garbage unit. Now I know they probably almost never hit, but that seems like they have at least one very nifty use. That use being running them in front of your Ogres, standing and shooting (thinking wide and thin here folks), and either being demolished in combat, or reforming for the bull charge. That last part however I'm a bit curious as I can't remember if they could reform (if they held) in combat without a musician, and don't have a book with me.
Either way this tact holds a lot of sway with me. For one, they provide cover to our meaty hides from that heinous missile file. It also seems like it would give us the charge more often, which is great for that impact hit goodness. It seems like a tactically sound decision. Plus it speaks to me personally. I'm a DE player who loves the sac dagger, and for those magic players, a monoblock player who considers life/creatures just as expendable as mana. And lets face it...
No one likes a Gnoblar.
So am I bonkers here, or does this seem like it'd work? Or is it common knowledge to use/disuse this tactic? Fill me in before I make two 30x2 units of gnoblars here.
