You know, I really like the way they implemented quirks in XCOM 2. When a soldier gets a fear of something--they have, in my experience, really
earned it. Like narrowly surviving an attack from a Sectoid or Chosen and then getting a fear of them, for instance. It feels really appropriate and not random.
In general I love how they've turned soldiers into "more than just numbers." It must've been a focus of the xpac, because most new mechanics tie into this feeling.
High-level psionic enemy should've been an upgraded sectoid (like in LW2), rather than yet another Advent reskin. Game needs less of those generic fuckers.
The two new ADVENT enemies tie into some of the SITREPs and dark events pretty well.
I don't think he ever got the chance to MC more than one dude at a time before I beat him.
It might not be his abilites that are weaker, but his AI. In my game he would summon zombies way too much, which is very easy to handle.
Yeah, that might be it. Purifiers kinda suffer from this too--they cause a lot of destruction, but not much actual damage.
And I guess Spectres too. Their threat is huge, but what they do most of the time is ineffectual.
