Hay there,
have to say that I am super bumped after realizing, that I no longer can play with my friends (except as a duo) in ranked mode, since I hit the Master rank.
The game currently no longer offers me a mix of team fun and competitiv competition since then. 
Now I get that Blizzard wants the Top Tier to be something special and I also support the general idea. But completly shutting me out from a team experience - since I am not fully counting the kinda derpy unranked mode - feels really harsh and punishing to me… and that for beeing good at the game.
I’d really appreciate a better solution for that conflict in the future seasons.
Because you kinda have to admit that it’s a team game most and foremost. And also people like me just don’t enjoy the solo experience.
