Wait, why is Outcast considered to be good against armour? Is it on the random chance you’ll face Leveticus?
There is 9, 10 with pride, models in the faction that can ignore armour in some way. One of them being analyse weakness and an ap trigger on Effigy. Another is a trigger on Viks secondary action.
Ressers have 5.5 (if you count McM 2 since he can get any action)
By comparison 10T has at least 16 models capable of ignoring armor, 1 analyse and 1 upgrade that makes any model ignore armour in melee
