We have a game like that. Its called ESO. Healers are also not needed in content and are just more of a buffer for new/bad/inexperienced players.

ESO is not a Holy Trinity game. FFXIV however is.

Raids while having become casual content, arguably shouldn't be. They are supposed to have mechanics for each of the three roles. Not having them in a raid is a red flag.
