Hi, quick note: thanks ot Sophia for the wonderful feedback, have made your NPC followers act a bit more cannily during combat: falling back if using ranged combat.
Also, more apparent how to Rally Troops during combat: Press 'K' to have followers fight everyone nearby, HOLD 'K' to recall your party - useful if they get 'stuck' (I call it 'in a red mist' but others might see it as plain old buggy)
