Third and final Chosen (Warlock) eliminated
Don't know if its because I 'got gud' or just because all my squad are Colonel rank but I found it fairly easy compared to fighting the Assassin and Hunter, especially the former.
Also, the Templar class is incredible at melee combat; just had a Chrysallid spawn next to my Ranger so used the Templars exchange move to swap places with the Ranger, then rend to instant kill it and then parry to block an attack from a nearby Andromedon
