Deflectors in High Guard Fleet Battle

[cometyo]

Sorry if this has been discussed already (I couldn't find anything on this), but how would deflectors work in High Guard's fleet battles rules? Would it be a dice pool similar to meson screens and dampers? Would it work more like sandcasters? Would it just be an add-on to armor (divided by 3.5)? What do you think would be the most balanced way to use them?

Like any other screen?

They work just like Meson screens and dampers, but for any damage. Presumably they should work the same (dice pool).
