This. A thousand times this.
I run Unmade and I played a game against SCE where the objective was kill each other's leaders. I lost on literally the first activation of the game. Onslaught on Longstrikes is absurd for any kind of "Kill specific model/detachment".
I know that the victory conditions are kind of unbalanced and really situational but what were they thinking allowing that much damage potential at such a range?
