i noticed this point but you must know if one list is able to crush you at the early biginning. And with nightfight rules and a bit of strategy it s still possible to benefit from this trick.
it s like being able to run a horde of psykers with one of the most efficient anti psy in the game. We don t know if we ll have a decent AA solution, we have a low tier codex and most of our units are overpriced or glass canon. did i mention that in a shooty metagame the lost of any solution to assault from reserve isn't really good news.
So i try to point out everything we can take advantage of.
And just to mention, i din't see any mention of distance in regard of enemy units during deployment. So sporemines are really useless now. THey are worst than before(i never imagined i'll say something like this one day).
