Overwatch needs role queue in basic structure of the game

[GreyFalcon-11737]

How about this idea instead:

Role Queue with Team Compositions:

• Choose Competitive.
• Given a selection of team compositions sorted by most popular at the top.
  • 6flex at top regardless of popularity.
  • No Damage hero spots, just Flex/Tank/Heal.
  • Locked roles, but instantly unlocked if you get a leaver midgame.
• Pick team composition out of 18 possible compositions (maybe less if you take some out).
• Pick role you want in a team composition.
• Start queuing.
