It's a little more nuanced than that. The irony is that rolling hots across the group would actually be the superior choice. You get the same damage and you have continuous healing rolling on people as mechanics mitigating risk and just overall making things comfier. That's before we touch on the advantages of an instant cast Regen for mobility and timing vs Glare's short cast time. I did something similar for Hello World prog, rolling regens and precasting Medica II en route to my spot to reduce the risk of a ranged dps death in certain combinations.
it would just be.... weird and counter intuitive IMO.
