IT’S A BUG FIX NOT A BUFF
No, this is not semantics.
Back when Moira’s healing was bug fixed the Devs explained that a bug fix is when they fix something that went under their radar as an unintended featured (i.e. Moira’s healing through barriers)
Zarya and Symmetra’s beam were acting in a different way they intended them to function
Is Symmetra owning you more now and this makes you super salty? That’s a whole different subject my man
DO NOT FORGET Symmetra can still be killed the same way she’s always been killed: from a range or faster than she can uptick her beam.
