enhanced icebeam does not scale damage at all if you freeze your opponent with it mid air. Doesn't matter if you combo it after a knockdown move(224) or they jump into it; will not scale your damage.
also the enhanced ground freeze breaks the double freeze rule if your opponent falls or jumps into it.
example 1: opponent jumps into your enhanced ground freeze. You can do 22~freeze and it WILL freeze them again allowing you to continue your combo
example 2: you combo 212~iceball and then use enhance ground freeze. Opponent will break from ice and fall into ground freeze and be refrozen standing up.
the enhanced ground freeze is impractical and will scale your damage to the extreme so it's not really an advantage but the enhance icebeam does give more damage than it should when the situation happens
