Nothing in the game can hurt him if he's not on the table, its a non-issue. It feels like you're arguing just for the sake of arguing.
Again you should check your math. 9 shots, 2/3 hit, 1/3 wound, 1/3 save. Seems to me ravager's doing just as good a job as the venoms, and at 25 less points.2 Venoms (without crew) 1,333 wounds on average
Ravager: 1,111 wounds on average
So... in what world is 1,333 worse than 1,111?
Pretty big mistake in language, but whatever. And I never said lances on the ravager. Beyond that, if your opponent is rolling badly enough your venoms kill his knight, odds are you could have killed him with anything."Probably kill him" was a mistake in language in this case, I meant a chance to kill him. Because even in the best circumstances where the ravager hits and wounds all lances while the dredknight misses all saves he will score a maximum of 3 wounds, while the Venoms (with an outlier in saves) could possibly kill him.
