Swooping hawks - do I actually use them ?

Hello everyone, I've been painting like a demon for the last couple of weeks. That combined with work and my shiny 8th edition fantasy rulebook have conspired to keep me from the blog. Today I wanna take a look at 2 army lists I have thrown together in between running around. I'm not entirely satisfied with either of them at present as I feel they lack focus. The first list:

HQ:

Farseer with Guide, Fortune, Spirit Stones and Runes of Warding - 140

Troops:

10x Dire Avengers with Exarch, Shimmer shield & Power weapon and Blade storm. They are mounted in a Wave serpent with spirit stones and a Shuriken Cannon. - 272

10x Dire Avengers with Exarch, Shimmer shield & Power weapon and Blade storm. They are mounted in a Wave serpent with spirit stones and a Shuriken Cannon. - 272

5x Rangers - 95

Elites:

6x Fire Dragons - 96

Heavy Support:

1x Falcon with Missile Launcher, Holo Fields and Spirit Stones - 180

1x Fire Prism with Spirit Stones and Holo Field - 160

1x Fire Prism with Spirit Stones and Holo Field - 160

Fast Attack:

1x Vyper with Scatter laser - 60

1x Vyper with Scatter laser - 60

5x Swooping Hawks with Exarch, Sunrifle - 153

1648 Points

Well the upsides to this list are that I get to use a bunch of units that never see the light of day. Rangers, Vypers, Swooping Hawks, fire prisms all units that I never use. It's fairly mobile and has a decent amount of models in it. It puts down a whole bunch of vehicle hulls and almost everything is fast. It's got decent anti tank and anti hoard options but I feel in general it will suffer. However I'm willing to make a go of it and see what happens.

The Second list I threw together:

HQ:

1x Eldrad (refluffed to suit my Iyanden) - 210

Troops:

10x Dire Avengers with Shimmer shield and Power Weapon and Blade storm. Mounted in a Wave Serpent with spirit stones and Shuriken Cannon. - 272

10x Dire Avengers with Shimmer shield and Power Weapon and Blade storm. Mounted in a Wave Serpent with spirit stones and Shuriken Cannon. - 272

10x Guardians with Spirit Seer and Embolden using a Scatter laser - 131

Elites:

6x Fire Dragons with Exarch, Tanks Hunters - 123

Heavy Support:

1x Falcon with Missile Launcher, Holo Shields and Spirit Stones - 180

1x Wraithlord with Brighlance and Missile launcher - 155

1x Wraithlord with Brighlance and Missile launcher - 155

Fast Attack:

5x Warp Spiders with Exarch, Withdraw, Twin Death Spinners and Power Blades - 152

1650 Points.

The Second list is pretty decent but it got torn a new one by a shooty marine list before severely denting my confidence in it. I'm considering swapping the Guardians for rangers and the wraithlords for Fire prisms. Any feedback would be welcome. Anyhow that's my bit for today, let me know what you guys think.
