Ah, see, I don't care if I run "an actual healer," whatever that means.
I run a FFXIV Sage, I enjoy running an FFXIV Sage, and whether that means I'm running "an actual healer" is irrelevant. All that matters is that, for me, it's more fun than, say, running an FFXIV Dancer or FFXIV Warrior (both of which are OK, BTW, but I enjoy Sage more.).
If I read you right, and apologies if I haven't, you set your heart on running "an actual healer," whatever that means, and then subscribed to a game that does not offer that option. Now you want the game to change to suit you. I don't think you're entitled to that, and I don't think SE is going to do that, but feel free to keep asking. Damn shame if that's making you unhappy, though, because it's your choices that created the situation.
