Pretty clean. Pretty basic. Pretty solid. Pretty boring.
Point costs are wrong. Grey Hunter packs are 170 points as listed, not 155.
I'd try to bring some Wolf Scouts myself. Maybe this:
Could always swap the Flamer for a Meltagun and drop the Melta Bombs on the Rune Priest but if it were me I'd want the Meltabombs, just in case. The whole army has transportation. At 1000 points you don't strictly need 2 units of Long Fangs. They have split fire and their own Razorback so you have a fair amount of ranged shooting between them and the Rune Priest. I would recommend dropping
JotWW for Storm Caller or Murderous Hurricane though.
The Wolf Scout unit can OBEL or Infiltrate of course. Double Melta and double Wulfen can be fairly nasty, and you have 4 models that you don't mind sacrificing before you get to the important ones.
