How can we really define Healers?

[KDSilver]

Healers are DPS with varied healing toolkit to support, protect and heal the party when needeed.

I think the term "Healer" and what it contains depends on the actual game where you talk about it.

A Healer on FFXIV will have a different skill set than a Healer on WoW.
On some games, Healer's doesn't even exist in the "general meaning" of what it should be.

So, I guess we can say that FFXIV are healers the way they are, because they are designed like that, and not because of what we actually want them to be.

Of course this doesn't mean healer on FFXIV can't evolve to have some great improvement, either on the healing parts or the DPS parts of their kits.
