Completing (because sometimes only 1,000 chars is simply too few):

And I am also from those that thinks that a caster class must be always casting. But it appears that for the community that healers must DPS before everything, even healing.

And is from that misconception that they think that shame healers that don't meet a minimum DPS number is a good idea. And when healers begins to obey that numbers (to not being shamed), that comes another cargo of crap because they aren't healing anymore while the first problem is just worsening, adding more pressure into newer healers that's yet far from even doing savages. And all the crap generated by this misconception is what is scaring off the healers.

If we want more healers, as community, we must make healers feel welcome. That's how we can attract more people to healer jobs (and drop the queue time for DPS jobs).
