Summary:
Competitive play:
No concrete date, Unlike in the beta you can now drop down a tier. If you lose, you're going to go down, if you win, you're going to go up. Matchmaking will be like quick play; party with X amount of friends and it will find another party of X amount of players of the same skill level.
Tick rate:
Jeff thinks people are getting confused. The server does tick at 60 Hz, it's the client update rate that is lower. The custom game high bandwidth option is buggy for 20% of players, the more it gets tested the more likely they'll roll it out to quick play. Very irresponsible to roll out something so buggy. He thinks players blame the tick rate too much when things go wrong but in most cases it's the fault of latency.
Balance changes:
McCree nerf: Coming before D.Va buff. Reducing the Fan the Hammer damage. Want to keep it so he can flashbang then fan the hammer someone like Tracer but not destroy Tanks.
D.Va buff: Unclear what to do right now with her. Might look at her damage or survivability. When they do buff her it will be one direction not both.
All platforms will get the balance changes at the same time unless one platform somehow lags behind.
Play of the game:
Thinking about improving saviour play of the game as it only shows in 1st person camera. Showing them more "cinematically" would help this.
Future content
Look out for more info on new maps and/or heroes later in summer.
Players haven't found every in-game hint about new hero.
Cross platform with PS4 and Xbox One:
Very open-minded about it.
