We already have a "Formation Leader" special ability in the Tau list now with Bonded Team, I was wondering how long it would take until we got a "Formation Inspiring" suggestion. I think both could be useful, which is why I'd rather see them as special rules for units (i.e. listed in 2.1) than in these one-off army list notes.
We can come up with better names, but what I'm suggesting is something like this:
Quote:
Formation Inspiring
Some units or characters are noted as being formation inspiring. A formation that includes any formation inspiring units when working out the result of a combat adds +1 to the result roll.
Quote:
Formation Leader
Some units or characters are noted as being formation leaders. A formation that includes any formation leader units may remove one extra Blast marker whenever it regroups or successfully rallies.
On whether or not HH should have that, maybe. I agree with kyuss that we don't see HH much is due to the Mech Coy being expensive to start. Sure, you could give them to a Infantry Coy, but then you're given up garrison and slowing down the HH. I'd use a 3-6 strong HH support formation though, or take them if Mech Coy's were smaller/cheaper (in a variant list).
