I would like to have a confirmation/clarification on the effect of ATTACK & DEF skill points on my Hero Stats.

If I remember correctly in the first AMA it was stated that ATTACK & DEF skill points should not impact Hero Stats.
I can still see that today they do impact Hero Stats, in the same way as they impact the Equipment Stats.

Is the impact of ATT & DEF skills on Hero Stats, that we are observing today, a bug and will it be fixed in a next update or was the original statement incorrect and is it working as intended?
