I was planning to use a squad of sisters of the watch in my coalition
AOS army (Stormcast Melee with Aelf ranged support), however, I didn't realize the same kit can make either unit....so now I'm questioning how powerful the shadow warrior ability to reposition befreo the game starts is...vs the superior offensive abilities of the sisters.
Please let me know if I'm not allowed to post point values....but for an additional 40 points the Sisters of the Watch seem to be much more deadly in raged combat compared to the Shadow Warriors. Now, that being said, the Shadow Warriors ARE cheaper, and they do have that nifty ability to reposition at the start of the match, along with their nifty reroll ability if they are within a certain range of cover....
For your consideration, the sisters warscroll (240 pts a unit):

And the Shadow Warrior's warscroll (200 pts a unit):

And yes....I do know I could just buy a 2nd box....but please, my poor wallet is stining....I've already bought about $200 worth of elves this month thus far!!
