There’s an AMA focused on Hero Design/Balance coming to Reddit on May 9th:
It’s cool that the dev team continues to do these, but I really wish they’d host them here on the Official Forums as well (or at least announce them here). It’s frustrating to feel like a second-class community.
People rarely plan ahead to participate in these sorts of things - I was talking about having another announcement thread (like this one, except more blue) posted to ensure that nobody forgot and/or missed out.
Maybe we can get a better idea about their philosophy on Fantasy vs. Gameplay when it comes to designing heroes who have playstyles that are relatively subjective like Tassadar and Garrosh.
