I run a noise marine army and I am very happy with their versatility. I wouldn't worry about having more CC dedicated squads as they are already a solid CC unit. With the bolter (or sonic blaster) AND a bolter CC weapon combo they will always have 2 attacks. I would recommend:
- splitting your 10 man squads into 2 5 man squads (giving you 6 troop choices).
- adding an asp champion with a power weapon (thats 3 I6 ignore amour save attacks)
- Adding blastmasters. They are really versatile and will give you more tank busting or marine frying power
- Leaving one marine per squad without a sonic blaster, no reason to pay the extra points when you will always loose a guy per squad.
If you have problems with the points I would recommend possibly going down to five 5 man squads.
