Getting frozen is an instant death sentence. Remember when they nerfed Fusion grenades? Same problem. Except that the melee, the grenade, and the super all end opponent supers with ease, and result in an easy kill. Getting frozen every time you pop around a corner is extremely frustrating.
You can't freeze bosses; they only get slowed. Why can't stasis work like that on guardians? Or at least on guardians in their supers?
And to those that argue for adaptation: I generally agree, unless it makes normal thing no longer viable. People should mostly get to play what they want. And it's unreasonable to think it's possible for everyone to adapt strategies such that they all never get frozen again.
