I can understand it not being needed at all in the feast if you have a competent tank but in frontlines almost all the tanks are "guarding the base" in tank stance or just chasing some brd. Even with 2 competent tanks in the team its not enough to chase 101325 healers that can just kite for days while melee do no damage due to server ticks. Before anyone says "git gud" , I'm not saying its needed but it would definitely help the melee who have to risk their lives to dive into 8 people to kill a healer unlike ranged.

P.S. : I'm totally from a japanese data centre so SE should take this seriously and implement it next patch.
