Anons, hear me out:

Demolisher cannons.

>Strength 12 so will pen AV 14 on a 3+
>24" range, enough to threaten anything in no mans land
>Blast, almost impossible to miss large targets like vehicles in the new rules
>3 damage, Ordnance (D) so 6 damage when stationary
>One vindicator with demolisher is only 140 points
>Two vindicators combined to up to 12 damage, enough to one-shot a spartan whilst still being cheaper in points
It might be time for the humble vindicator to shine once more
