Anti-Mech List

After reading about all the Mech lists that are so prevalent now in the tourney scene, I've been thinking about how to counter it. I think that Mech will suffer against a lot of high Strength and AP ranged weapons. I played around with this Marine list as a potential spoiler for the vehicle heavy lists of today. Think Combat squads for all 10 man marine units - Dev heavy weapons split equally between the combat squads. Open to your thoughts and suggestions.
