The most important thing from the Drukhari Faction preview:
GW has finally remembered that they described the non-KEYWORD interaction in the 10th edition rules commentary.
And then never used it.
Meaning, you now get your buffs/ abilities/ triggers against a wider variety of enemies, as you can see with the Wyches getting LETHAL HITS: non-MONSTER/VEHICLE
A lot of buffs (maybe I'm generalizing that too fast for other factions, it is especially true for Dark Eldar) only work against Infantry models.
Most egregious example being all of the previous poison weapons from DE, DG or Guard becoming ANTI-INFANTRY X+.
There is a chance, that, with coming of your codex in 11th, you will actually be able to wound Horses and several other creatures with lungs and a circulatory system with your fancy future venoms.
And always remember
Hope is the first step on the road to disappointment.
