I also feel lost on this issue, some say it matters and others say it doesn't matter, I've already done some tests myself and tested all the feohs and what "forces" them to use the attribute would be the "destruction" skill that is the only skill of each feoh that deals elemental damage, the other skills don't hit more or less if you use any element but the "instance" (Wind, Holy, Fire, Dark, Water, Earth, etc) has an extra bonus Example: Wind = M.Skill Crit Damage. so the wind would do more damage on the critical for being a "bonus" and not an "attribute attack" and it does the same damage with any attribute you use on the weapon. But this is a subject that leaves those who really want to know the truths of the game very CONFUSED, it would be interesting for some GM to do these tests for us and end these mysteries of l2 once and for all
