Their Lash Out ability is far better then the Lineman counter attack. When they get struck they strike back, and with a range, which means that this is one of the only units that get a counter strike against bounding flourish. Add the mastermind in and they have the ability to eliminate units before they strike. And with the fact that the lash out has a 2" range, you can assume that is is truly some form of short range psychic backlash.
While a ranged unit would be different, the game truly is melee centric, and a ranged troop unit would have a field day chewing up their opponents (unless there were some major drawbacks to their ranged ability, which would basically make them useless to play anyways).
I wouldn't say far better. They have to survive the hit for it to trigger and it's only a rate 1 melee attack which then has to get through their opponents defense chart. The linesmen have a 30% chance for a rate 2 attack with the benefit of Follow-Through. It clearly depends heavily on the Brood's defense chart, wounds, and resilience which we know nothing about.
It may prove very useful against Bounding Flourish provided the dancer doesn't land > 2" away (which is possible; this is assuming the dancer has to land before being hit).
When I mentioned "ranged" previously I did not mean a ranged attack. I was referring to some sort of quirky "utility" skill (similar to Come Hither) which could be cast from ranged and used to manipulate the battle in some way. I suppose the Lash Out
could be some sort of psychic blast, but it's a melee attack and some of the Brood sculpts have daggers. I read it as "you hit me, I throw this small dagger at that guy".
Don't get me wrong, I like the Brood and I'm sure they will see lots of play time on my table but I was hoping for some tighter connections between the lore and the abilities. Or a little more variance in the units. Right now Teknes seems like a "group everything up and wait for the enemy to do something" faction.
Teleo made some great points when he mentioned the units for the other factions. Even though I'm playing Teknes I would like the option to pick a different combo of units and "go on the offensive". After reading their lore, I was hoping the Brood would lend themselves to a slightly different style since both linesman and union workers already fit the "reactive" bill.
