Just want to verify with some of the knowledgeable folks out there: hordes get their armor and toughness value against these types of weapons, correct? Just checking as we played a game the other day wherein a frag grenade (blast 5, p0, meaning 5 hits to the horde) could basically do nothing to a horde of Termagaunts with their TB of 3 and armor 3, which seemed a bit odd as the grenade could do damage to an individual gaunt outside a horde with it's 2d10 damage.
It made me think that possibly the blast and flame weapons are supposed to ignore armor and TB, which in a way makes no sense, but neither does a frag grenade doing nothing!
Thanks for your input.
