It’s not a skill check to NEVER LOWER BARRIER! ALWAYS BARRIER!
Overwatch has too much of a reliance on barriers for everything. I say that even as someone who mains bastion.
You can’t just NOT use your barrier because there’s an ana on the team and save your barrier because Ana MIGHT throw a bio-nade.
It IS.
But Rein is the anointed one, he can’t have his party spoiled.
