Since you need multiple DD jobs in a party, they're a lot less competitive. Yes, you might do better if you stack all of one, but so what if one of five DD aren't the optimal class? But if there were two healers, anything that gave either an advantage (whether real or just invented by popular opinion) would make the class the ONLY OPTION in the closed minds of FFXIV players.
With respect to AoE heals, there would be obvious situations where AoE low healing would make that class the ONLY OPTION (if a mob spams AoE), and situations where a high-value single-target healer would be paramount to success (anything else). That's not doing anything for making interchangeable healers of equal efficacy.
