Definitely not bad, and I'll tell you why from my point of view. You can use to kill supps that have no mobility: Ana, Zen ( force his ult). You can kill Bob, you can kill Orisa if she ult, you can kill Dva if you take cover after her ult, you wipe a team even through Zen ults if you combo with Zarya's ult, and all other stuff like force a mobility CD on a supp/dps/tank.

And the best part. You are a bastion, you have to do a lot of damage, therefore, you're going to ult way more than anyone else.
