I like picking up more razorwings. But if your friends are down on them... That's tough. I like to have at least 3 in my bigger games. They almost always get their points back the turn they come in. Also, I've been having a HUGE success with the Corpsethief Claw formation. It single-handedly won me a game last week against 'Nids. So... If I'm you my next 5 purchases are 3 Talos and 2 Razorwings. But Amish is right... You've got a ton of stuff so it's really up to you. What has been your experience? And what are you trying to get out of the army?
