And here we arrive at the problem: they all do the same thing in the same way (pretty much). In older versions of WoW, you had healers that did mitigation, healers that did healing over time, healers with big casts and big numbers, healers with AoE etc. Back in Wrath, none of the healers were even remotely the same. They all had highly distinct playstyles and toolkits. You can't get even close to claiming the same thing is true for healers in FFXIV. You have to argue semantics to even create a worthwhile arguement because that's just how similar the healers are.
It's the laziest design of all.
