*Allows free flight, 300hps, constant self regeneration, increased movement speed and the ability to rez when flying for 15 seconds which is the longest non placeable ultimate in the game* - is useless
It's a watered down Zen/Orisa ult but I wouldn't say it's useless. You just need to know when to pop it for them team fights. I typically damage boost instead of heal and then heal up afterwards to get that ult charge again.
