Vayl1 - Seraph or Naga

I have been playing a lot of Vayl1 at the moment to see if I can build her into an anti colossal list. I have come to a conclusion - I hate Leggionairres with her at 50 points. At 35 I loved them, at 50 they don't do their job which is to protect my beasts after I feat. So I am back onto hex hunters which is a problem because there is not two points in the list that I can spare. That leaves me two options:

1. Drop the Seraph:

Legion of Everblight
Standard Army
PCs: 50 / 50
27 models

[00] Vayl, Disciple of Everblight (0 / 6 WB)
[12]  >> Typhon
[09]  >> Scythean
[09]  >> Scythean
[05]  >> Naga Nightlurker
[02]  >> Shredder
[02] The Forsaken
[02] The Forsaken
[01] Blighted Nyss Shepherd
[08] Blighted Nyss Hex Hunter (9 grunts)
[03]  >> Bayal, Hound of Everblight
[03] Spawning Vessel (6 grunts)

I know the response to this is generally "why are you playing a Seraph?" but Vayl has a lot of assassination potential and the Seraph really helps with that. In addition under incite it has a d3+1 RAT 7 shots at POW 14. It can often aim for RAT 9 and boost all 4 damage rolls if you roll 4 shots at which point it is taking a heavy out of the game. It is good. That said the Naga gives me blessed which is pretty much essential of I want to kill a stormwall. 

Option 2:

Legion of Everblight

Standard Army

PCs: 50 / 50

26 models

[00] Vayl, Disciple of Everblight (0 / 6 WB)

[12]  >> Typhon

[09]  >> Scythean

[09]  >> Scythean

[08]  >> Seraph

[02]  >> Shredder

[02] The Forsaken

[02] The Forsaken

[01] Blighted Nyss Shepherd

[08] Blighted Nyss Hex Hunter (9 grunts)

[03] Spawning Vessel (6 grunts)

I recognise this list. It's my old Vayl list pre Naga. I know it's good and I loved it to pieces but no naga means that the Stormwall may be an issue. 

I think I'm going to have to go with the first list. I really don't like the Naga but I think I need it.
