Agility is easy path, not the best path. You still take same amount of pleasure and sentivity damage for every evade, and every counter attack, because they are counted as an action, or move. Every non willpower and mind action, performed by either karryn or enemy, deal pleasure damage with a fixed base of 3%, its the least amount, and idk amount of sentivity.
For virgin runs, agility trades raw damage for evades and counterattack by a lot, prolonging the fight and increase amount of turns, or move/action performed, filling pleasure bar, that is already hard to maintain, at a much faster rate
Pure agility run doesnt doesnt let you make first moves at mid/late game, game balancing would buff every single enemy stats to hell and every single one of them will have every single stat higher than yours, every turn after the first, they will move first.
For balanced run, agility damaging pleasure/sentivity bar, shorten your "fight" phase and move to "sex" phase much faster, where it becomes a non factor.
For slut run, agility never exists.
Ironically for the name, agility lacks flexibility.
on 2nd thought, as I think of it. Agility does have uses for sex fights: It damage pleasure and sentiviy while retaining your stamina, leads to much safer transition to sex.
