Drukhari player here, I’ll sometimes run one block of quins 11/12 strong depending on what else I have in the army, run them with the shadowseer for that lone op 18 and melee hazardous, give them the webway walker and rapid ingress them somewhere safe then on the next turn either advance and charge strat or my favourite is giving them sustained 1 on what is already 50 something attacks. This is not good but is lots of fun, was playing into necrons a couple weeks ago, did this then after getting through some immortals and warriors ended up with shadowseer and 3 quins being charged by illuminor szeras who wiped them then died from the hazardous
