Battle Surgery Ancillaries

[HopliteElite]

Ive noticed that unlike my version of frome based on 2.1, I cannot add the doctor ancillary to evil generals anymore, just the good ones. I can get lash of lugburz as evil but I'm unsure how effective battle surgery +1 is compared to the doctor. Has anyone done any comparisons? I like playing as Isengard but I hate losing the vast majority of troops to scratches, especially expensive and timely to recruit ones like berserkers.

You could increase the battle surgery of the lash to the equivalent of the doctor. Personally, I never noticed the difference between high battle surgery and no battle surgery but that might just be the way in which I run my campaigns.
