On SWTOR, back in the day, wait times were sometimes over an hour even on a healer. Can you imagine DPS wait times? Yep... DPS wait times are nothing new. HW added a tank and healer so they sped up for a short while.
I wouldn't mind them making the upcoming dungeons 1 tank 1 heal and 4 or 5 DPS. Might slightly speed up the wait times. Not sure if it would be enough to really make a difference though.
