Yeah, no, every tank plays differently, and just tanking damage isn’t the job.
When that Ball or Winston dives a Widow off high ground, that’s making space. When Roadhog shows up and the enemy DPS hide from hook, that’s making space. When the Ball dives a backline, eats nade, sleep dart, and likely another cooldown and gets out, those aren’t available when the teamfight starts.
Just getting shot? That’s not making space. That’s just feeding ult charge.
