2k space wolves, like them nice and fast

On the praetor take an normal lightning claw, the 10 extra points isnt worth the loss of rending and the gain of reaping blow. He has Ini5 and you want to use that, so give him an paragonblade instead of the hammer.

The caster of Runes will be useless when you go this fast. You will get more out of an speaker of the dead. Re-roll failed hits and 5+++. Boost your damage output and survivability.

You might want some anti tank on your assault squads, or some heavy hitting stuff.

Contemptors are very good, but unless you play against a lot of fliers, the target array isn't doing anything. Dump them and give assault squads melta bombs.

What is your game plan? You are fast, and likely be in combat on T1. But your units aren't that durable. One unit of terminators can ruin your day.

So the rune priests are there for some 3+ shrouded giving my units some survivability outside of combat
Melta bombs vs ws5 on comptemtors I can't see them being very usefull my answer for terminators is ither run away or hammer preator with dreads
Your right about the targeting arrays though they where useless
Definitely needed more ap2 / high strength in the assault squads weight of attacks just wasn't enough
