Post here exactly what the formula is as you put it in your skill. Because the only way for it to increase is for the formula to have changed. Also keep in mind if there is variance, then an increase of 10 is not unusual.
Edit: If I see it right, your have the / 2 inside the () now, and initially it was outside the (). That will cause a difference in damage too. Though I did notice you have a 20% variance in your posted skill, which will also factor in, as even a calculated damage of 50 that means you will do 40 - 60 damage due to the variance.
