greetings brother!
overall i quite like your new list. however, a couple things from my own experiences;
- try swaping the dread's twin-las for a twin-autocannon. best transport hunter you can get! i used to use one untill the 4th edition marine 'dex came out and this guy never disappointed me. he would quite reliably immobilise or outright destroy whatever transport he shot at! (av12 vehicles were a bit harder, but the 2 shots usually assured at least 1 glancing hit.
)
this can allow your heavy hitters, (devies & pred), to focus on the main battle tanks!
- lose the power weapon on your ravenwing sergeant. space marine bikes don't belong in combat as they are no better than tactical marines!
use those pts to give them meltas or flamers instead... (my first 40k army was a pure ravenwing! if my bikes got into assault then they just died!)
another thing though, wouldn't you have to roll 1st for the chappy to see if he arrives with the deathwing? (as they are 2 seperate FOC choices) might mess up your 'uber assaulty death squad...
also, i doubt the deathwing will go unharmed! (*cough*satchel charge*cough*!) unless of corse you have the option of landing them out of sight!
i'd love to give this army a go sometime! it looks like a fun list that will present a good challenge to anyone... especially if they're unprepared for the deathwing strike and the spliting squads!
cheers!
