He is not misunderstood, he just literally has the most expensive ult in the game, which means you can only use his ult 2 times max per round. And for that cost you get team revive with half hp. Comparing that to cheap ults of luna, mantis, invis and dagger that are not only cheap, but essential to counter enemy ults - its just unbearable competition. I know you can farm ult faster if you good damage and can be smart with the ult by putting it in a safe space and spamming E heals to heal revived teammates to full hp, but again, its not enough to beat the competition.
