When someone recommends a game to me, I first ask "is it fun?" The same is true if someone were to recommend a different class, different build, content I don't usually do, etc.

If the people who normally play healer say that healer isn't fun, then it doesn't matter how much Square intends for it to attract new players, why would they stick around when the people who supposedly enjoy it most don't even want it? It's one thing to lower the skill floor so that new healers can get a feel for the job without getting too overwhelmed, it's another to do what Square has done and crash the ceiling to the ground.

Quite frankly, the floor should be raised a little; we're at level 100 now and we still don't have enough incoming damage at a decent frequency to justify the amount of healing healers are capable of.

If we want the healer population to grow, you first need to get people to find it fun; making it easy is only a short term solution. Word of mouth can do the rest.
