yeah, but there isnt the demand. iv been playing...three or four years and have seen neither of either army you want in plastic.
Partly true, but also 'chicken and egg'. If there were plastics for customisability, and support with a new Dex that makes them competitive- you'd see the armies. They are very characterful.
and there arent enough sisters to playh in a apocolyptic scale battle fluffwise.
I call Bullshit. There are far more Sisters than Space Marines. Each major Imperial World has Ecclesiarchy buildings guarded by Sisters, whilst Cardinal worlds house Orders of Sisters in the thousands.
The Sisters can mass quite a formidable force to lead Crusades- just check the pics in their Codex, I have no idea where this concept that they are a small police force comes from- that's the Arbites.
so really theres no need to complain, just and add some marines or guard to fill out the ranks.
Generally a lot of people collect Inquisition armies because they've done the Marine army and got the T-shirt. They're bored of it, or they are not interested in them, or they just plain like an Inquisition army.
It's like telling a Ork player to throw in some Tyranid models.
As for whining about not getting new releases for Sisters, etc. with Apoc- deal with it, if your playing Inquisition you should be used to getting nothing.
Build one of those massive Cathedra tanks from the pictures in the book. Increase your Sisters/ Grey knights army with some of the stuff you'd never touch before (Repentia, etc).
Rumours of a VDR mean you can create new Sister/GK vehicles, etc.
