I think most of us has seen the formation leaks from WD, so what are your thoughts about the bonuses each formation provides?
I don't think any of them will get objective secured, maybe the core ones, but it's not for certain.
My thoughts are that the formation with defender guardians may get a bonus to cover saves, night vision or possibly anti-air.
The formation with storm guardians may get furious charge, preferred enemy or shred.
Windrider formation could get skilled rider or outflank.
The Avenger formation may get 5++ saves in CC, defensive grenades or some kind of defend ability, like reducing any opponents attacks to 1/model by forfeiting all of their own attacks.
