How about a non-support ranged dps?

[Archaell]

Ok but this isn't Warhammer etc. Unless this new healer job were to have high defense...

Of course they would need better defense, but I imagine it something alongside melee dps.

...

There could be ways around it. For example the melee healer could build up resources in melee combat while having abilities at hand when they can't be in melee. They would of course need some range healing skills. For example the red mage could be based aroud using teleports to jump between melee and range. Or they could have a "dummy" to which the negative effects would be redirected and which could soke up some damage for them.

Melee healers are not entirely impossible, it would just require some development time and I believe it would be unique playstyle from the current ones, which makes it more than appealing to at least consider.
