Razorback Overload- Blood Angel Concept List

I was sent a list from GDNMW.  Check out his blog.  It's pretty sweet. Here is the list as he sent it to me and I will add some comments in regards to what might make it a bit more competitive.  The army is based on a 2,000 point list.

2000 Pts - Blood Angels LasBacks

Librarian, 100 pts
Shield of Sanguinius; Unleash Rage

3x
5 Sternguard, 180 pts
LasPlas Razorback

6x
5 Assault Marines, 155 pts
LasPlas Razorback

2x
5 Devastators, 180 pts
LasPlas Razorback


So, the idea is to inundate the enemy with AV11 with the ability to move up to 12" and still fire a lascannon at a target.  Late game objective grabs are also possible due to the razorbacks having the fast rule.  It will obviously struggle with AV 14 and hordes, but could stand a chance of crippling mech heavy armies. 

The first thing I see about the list is that the points are wrong.  The sternguard squads are 215pt instead of 180pt.  So unfortunately, this list goes past the 2,000pt threshold.  I personally would drop an RAS squad from the troop selection to free up some points to help provide a little more umph to the army.  While this detracts a little from the overall strategy of the army by taking away a razorback, I think ultimately, it will help the list out a lot.  What the list really needs it some additional firepower to really overpower the shooting phase and to also provide an answer to AV14.  So, here is my first attempt at keeping as many las/plas razorbacks on the table while making the rest of the army dangerous as well. 

HQ
Librarian- shield, unleash rage- 100pt.

Elite
5x sternguard, las/plas razorback- 215pt.
5x sternguard, las/plas razorback- 215pt.
5x sternguard, las/plas razorback- 215pt.

Troop
5x assault marines, melta, las/plas razorback-165pt.
5x assault marines, melta, las/plas razorback-165pt.
5x assault marines, melta, las/plas razorback-165pt.
5x assault marines, melta, las/plas razorback-165pt.
5x assault marines, las/plas razorback-155pt.

Heavy
5x devastators, 4x missiles, las/plas razorback- 220pt.
5x devastators, 4x missiles, las/plas razorback- 220pt.

2,000pt on the dot.

So, in losing 1 las/plas razorback, I get 8 missile launchers and 4 meltaguns.  This helps to answer the issues presented in the last incarnation of the list.  It provides an answer to AV14 through the meltas, but also via the fact that with 10 lascannons and 8 missiles should statistically do something to a land raider if needed. 

The missile launchers also double as a means for handling horde units.  Using frag missiles and laying out 8 templates coupled with twinlinked plasma fire and the rounds fired from the sternguard, horde units like ork boyz or tyranid termagaunts should be manageable. 

On top of that, the devastators have the ability to leave their razorbacks for cover allowing the razorbacks to come in and retransport units that get stranded. 

The librarian provides a cover save via shield and I am torn between using unleash rage to help make an assault squad a little fightier.  On the other hand, he could take lance and deploy with the melta-less razorback to provide a tank popping option there as well. 

I would love comments on this build and if the second incarnation is an improvement or not.  It is certainly an interesting concept forgoing a lot of what typical blood angels lists utilize.  So, let me know what you think.  Thanks for reading.
