Solo healing/tanking feels HORRIBLE to play.

Because there’s no way any of your 3-4 DPS are gonna peel for you or actually contest the objective. Most Damage players run off and do their own thing and don’t actually support the team oriented aspects of the game.

If triple or quad DPS ever becomes the standard meta, you’ll find that no one wants to play Tank or Healer anymore because constantly being focused and flanked without any help isn’t any fun to play.
