Think of Girth as your armor/defense. Potency is how hard you hit and Responsiveness is your speed/how fast you attack.
After 1500 rounds each fight becomes a draw. If your not getting any swings in then you need to increase your responsiveness.
On the other hand, if he is hitting you for 0 damage then he needs to overcome your girth/get past your defense by raising his Potency.
Hope that helps |
