Yoshida once said they make the ex primals/savage dungeons first then downgrade it. so by that train of thought i can see that savage is gonna be indeed savage, like f1 instead of 2 missles its gonna be 4 (there is 4 adds) as and example f3 could be double tether, 2 pairs with +-, f2 needing to use both of the gobmounts, f4 instead of 3 lines on someone it could be 4, even 5. extra number of legs with hp (he has 4 and only front 2 have hp).
