Now that I think about it. Jump pack destoryers have the potential to be stupidly annoying on your backfield
10 of them come down, you can't move away, you eat 10 Poison 2+ ap3 attacks. That's probably killing 6 tacticals in one go even if they can't charge after
And hilariously when they shoot at you next turn you can shoot back with more rad grenades.
Idk how many point they are going to be but any other options that deepstrike and do similar damage seem like they are going to cost a lot more
BA at the very least can do with with their angel's tears
