Stasis will be more usable at lower levels, as the spell dmgs will be higher than before.
Stasis will be able to still deal good damage, as stasis bonus damage now takes effect (average of all spell damage).
E.g. if i have 300% earth and fire, 200% the other 2 i get 250% stasis damage. Stasis also hurts the lowest resist of the opponent, unlike any other element.
