Support battery... I don't see the point of these now. Check out what they did to the shadow weaver weapon profile. It might be cheap enough to take vibro with.
Banshee's are an interesting change, will be interested to see how they go now they don't always hit first.
EML's are better now they take all ammo types. It will make kiting out WW interesting. I'm guessing they will become to go to upgrade for WaveS now.
Vypers... not really sure where these fit in now, cheap way of getting 2 shuriken cannons on the table I guess, A full units is going into the interesting to hide.
Chainsabres I suspect will get a FAQ shortly as I suspect there will be some heated debates of the current wording.
Fire dragons are going to pop some transports
Warp spiders, flickerjump sounds wicket, but I suspect its not going to pull them out of the fire that often. Exarch upgrade is nice.
Shining spears.. this is a weird unit for the point costs. The exarch power doesn't make much sense to me, it'd rather use windrider's with scat lasers against an MC.
Crimson hunter, the exarch upgrade with starcannons might make life interesting against AV10 flyers..
Fire Prisms get chain fire.. a single high Str shot for almost 400 points... Don't think we'll see to many of those squads floating around.
Nightspinner combined shots are better than the Fire Prism rules, I that might be rather handy.
Aspect Host could yield some nastiness.
