This. Devs ruined the support role when they made main healers, and when they butchered the non-healing support’s kits by making them hybrid role heroes. Mandatory healing supports is also a consequence of 2-2-2. Shield/Armor/other sustain utility supports could have still worked fine, they just needed executing better.
I’m still upset that both armor supports we got were poorly designed messes and effectively left the playerbase to play in heal-bot hell forever.
