I am torn between Raven Guard and Iron Hands. I am just getting back into 40k after 5 years hiatus. I played Dark Eldar (venom spam) before I quit and before that I played Black Templar's and Necron's back in 2004. Just looking for more insight on Raven Guard and Iron hands with regards to their strengths and weaknesses. If you know any generic competitive list for them it would be appreciated. Thanks in advance!
