Magic Crit Hit Rate and Magic Double/Triple/Quadrouple damage for weaponskills

Hello SE,

Why does not Magic Crit Hit Rate work for magical weaponskills? And in the same vein, physical weaponskills can add extra hits to their weaponskills to increase damage, but magical weaponskills are only limited to one hit.

My we have gear to not only increase/grant magic crit hit rate to magical weaponskills, but also introduce gear to allow magical weaponskills to either hit more than once or do double/triple/quadrouple damage?

Thanks much,

A humble Beast Master
