You've got so many melta guns in this list that it feels like a 5th edition list... You don't have to be so worried about armor in 6th Ed.

I know Wolf Priests and Blood Claws arn't considered the best units, but they're a cheap option that still have the potential for hurt.
Blood Claws cost exactly the same amount as Grey Hunters, but their characteristic profile is suckier.
The Rhino will generally head straight at the enemy and distract them by getting as involved as possible while the GH's and predator form up in the midfield.
So your opponent will shoot this Rhino first and then your poor blood claws will be stuck out in the open with their bolt pistols an meltagun. They'll have to run for two turns just to get within 12" to shoot their guns.
The speeders will harass / suicide as needed, or hang back to deny objectives late game.
Suicide yes. If you ever get close enough to use that heavy flamer, it will die on the very next turn. Again...You've already got a meltagun in all of your troop squads, why do you need two more in the Land Speeders? Or better yet, give all of the grey hunters plasmaguns intsead.
