The problem is, 3 Bikes with 2 shuriken and 1 HWV is only a few points more for 3 more wounds and able to melee.
I love Voidweavers, but they are not worth the points, they need to be 10pts cheaper (and Starweavers too), 93pts and 89pts is right for them, at that point they are equal points in wounds to Skyweavers but has 1 more gun, thats a good trade off for a shoot only vs a melee + shoot unit.
Really look at Troupes too, Wyches are more wounds and more damage for same points
Shadowseer are more than Farseers
Troupe Masters are more than Succubus (basically same profiles)
The harlequin book only has 3 viable units, Solitaire, Deathjester, Skyweavers.
