Yeah it’s the Most Valuable Poster program Blizzard have done for years on other games, for Overwatch we were just on the support forums, other games can have both support and community MVPs.
Basically if Blizzard see people posting useful information/being helpful to the community and are activity looking for MVPs at the time they will approach you, the new WoW program you can apply for but it’s different per game.
MVPs get to have a little more contact with Blizzard for feedback and support, aren’t paid or anything just we enjoy helping the community out.
While Overwatch doesn’t have community MVPs currently, it has support ones so you will see us with green text in the support forums once it’s active, or if you look at the old forums/other games you can see it. I’m actually the Australia & New Zealand MVP so I’m abit of everything for all games, WyomingMyst (I forget his number so can’t tag him lol) is the support MVP for Overwatch and trust me if it wasn’t for the fact he is at the OWL this week you’d see his posts all over the support forums, guy goes hard in helping the community!
