To those complaining about Ranked Team going away...

They aren't going away...

• You can still play Ranked 5s, it's not going away
• Premade Ranked 5s ... 96% chance to be matched against other 5s team
• Opening up Ranked Team que to other 1/2/3/4 grouped people small impact on Ranked 5s Teams

TLDR:

Ranked 5s team now have a 4% chance to face a team less organized (non 5s team)... This is an advantage, don't complain.
