That was some awesome viewing! Gotta love the pragmatism The Spider brings to his DE play. Influenced by him, I've been having a crack at MOAR Reavers in the local scene. They've been going at it 50/50, but when they win, they win BIG.
I've used a similar RJB build but I have been opting for Arena Champs as "LD epic fails" have happened a bit too regularly and mucked up my plans.
I used to be such an anti-squad leader person, too.
Kia Kaha, Dark Eldar players!
