Moira Main
From iWiki
A Moira main is an overwatch player who mains the hero Moira.
They are typically seen as low skill players due to Moira not requiring much mechanical skill to master.
The stereotypical Moira main is seen as a DPS moira flanking into the enemy backline and not healing their team.
"Hey, their Moira is DPSing in our backline again!"
