- Freeze Ray's damage is scaled by the 10s recharge time. This puts it in the same bucket as Blaze, TK Blast, Power Burst, Shout, Tesla Cage.
- Bitter Ice Blast has a 12s recharge time, the same as all the other snipes.
It makes sense to compare these powers based on recharge time and endurance cost because that's how the damage/effectiveness is scaled.
I don't mean Freeze Ray is the literal 3rd tier power, but usually you call an attack "t3" when it's the attack between the t1/t2 attacks and the snipe in damage. Semantics aside, you can just compare by recharge time.
