Evolving list: An overdue change

Its been a while since i reviewed my army list in any major way, over a month now, so i would like to go over it again and see what i can do to improve it. Looking back over the last month i have had a mixed bag of results with the list, so before i go crazy and rip it apart i'm going to look at it and see its strengths and weaknesses.

This is the list in its current form: Wraithstar V 2.1

Farseer – 140  w/ wraithguard

10 Wraithguard – 396

Warlock, spiritseer, conceal

10 Guardians – 95

Scatter laser

6 Warp spiders – 149

Exarch, 2 x spinner

3 War walkers – 180

Scatter lasers

2 War walkers – 80

Shuriken cannon

The Baron – 105 w/ wraithguard

5 Warriors – 60

Blaster

Venom – 65

2 x splinter cannon

5 Warriors – 60

Blaster

Venom – 65

2 x splinter cannon

Ravager – 105

3 x dark lance

My current record with this list is standing 50/50 with 2 victories and 2 defeats. 

Imperial guard - loss

Orks - win

Dark angels - win

Blood angels - loss

Looking over the battle reports the key to the victory has been not getting the wraithguard shot to pieces while the rest of the army takes out key enemy units. Against the orks the wraithguard took out the mega nobz and warboss while the rest of the army took out the boyz. Vs the dark angels the war walkers shredded the command squad while the wraithguard took out the terminators.

My losses have stemmed from my opponent taking out everything else first then dealing with the wraithguard later on. The imperial guard went for the dark eldar and guardians first then the wraithguard second, and the blood angels tried to take out the wraithguard, but used an expensive unit to take out my back units. 

Its pretty self explanatory looking at this, i need to protect my other units, not just my wraithguard. But the army list isn't the only thing that's a key to victory, my tactics are key. Vs orks and dark angels i took out his army piece by piece, against blood angels and imperial guard, i spread myself too thin. So in future games i need to go after a part of the enemies army, not go after everything. 

Anyway back to the army list. what units haven't been great for me? 

• War walkers: These guys have been good for me with the scatter lasers, but the out flanking shuriken walkers have very limited ability with their 24 inch range. Maybe if i can drop some points i can get the second squad scatter lasers. 
• Dark eldar warriors: Having 5 in a squad is hard to hold an objective, as much as i like the venom transport i want to try out a warrior squad with dark lance so i have another long range ant-tank shot if i need it. Plus having 10 men mean they can hold an objective if i put it in my back field. Loosing the venom will hurt then. 
• Warp spiders: Strength 6 shots? what's not to like? But deep striking is risky, so i will try a few games with them walking up.

The rest is more or less the same. So what will my new list look like?

Eldar/Dark eldar 'wraithstar' version 2.2

Farseer - 100 w/ wraithguard

runes of warding, fortune

10 Wraithguard - 396

warlock, conceal, spiritseer

10 Guardians - 95

scatter laser

6 Warp spiders - 149

exarch, 2 x spinner

3 war walkers - 180

scatter lasers

2 war walkers - 120

scatter lasers

The baron - 105 w/wraithguard

10 warriors - 115

dark lance

5 warriors - 60

blaster

Venom - 65

2 x splinter cannon

Ravager - 115

night shield

So that's the list, not a great deal difference but i hope the subtle differences will help. Having a cheaper farseer means i can afford more scatter lasers but i can't cast guide on a war walker squad, that will hamper one but help the other. Having the big squad of warriors might be useful, but i'm not 100% sold as i will miss the venom.

Tactics wise, i'm going to keep the wraithguard out of harms way for the first two turns i can hopefully devastate what ever unit they attack. Also i will take down half the army if i can instead of taking the whole army on.

What do you think? better or worse?
