Yay for Lag (I shall not forget you) and Dano!
Anyways, I hope they won't turn out to have that spongy feel, like in Halo 2, you can sink hundreds of bullets into them and they just absorb it, doing nothing at all. I hope in SPv2 that you can kill with with around half a magazine (thank you warsaw/ace for correction) of BRG on easy, and a magazine or two for legendary.
