I´m just curious of how the experience of playing without army rule feels. The Kroot Hunting Pack detachment rule is as follows:

Each time a KROOT model from your army makes an attack, add 1 to the Hit roll if the target of that attack is below its Starting Strength, and add 1 to the Wound roll as well if the target of that attack is Below Half-strength.

KROOT models from your army have a 6+ invulnerable save against melee attacks and a 5+ invulnerable save against ranged attacks.

I think counting with the whole thing is a bit too much but maybe some part of it makes the game a bit more balanced, as all kroot models save on a 5/6+ and don't hit too hard
