So, it is clear that GF wants sun and rain to work as the offensive weathers with abilities like chlorophyl/swift swim and the damage increase to fire/water moves while they want sand and hail to be the more defensive types with the spdef increase given by sand and the defensive power of aurora veil as a move and abilities like sand veil/snow veil. Given this premise, how would you turn sand and hail to be more offensive and sun/water into a more defensive weather ? How would you fix the weather of your chosing to be adapt it to your playstile ?
