So initial viewing
Glissete weapon profile seems really good makes me think that the Glaves are special weapon like the one the Kairic acylotes where is one in three of them have it.
Slaangor guys profile seems crazy too and he has three wounds, he maybe a unit champion or Slaangors are going to be more elite then Tzaangors are
Bow attack if represent in a unit is decent, basically better Namarti reavers with rend
