Do you think that Picto needs a nerf?

Except they do not. Caster balance is awful, nobody is going to deny that. However, that is entirely separate problem from melee.

And in fact, it's a way to balance the casters, where all of them prefer to play PCT (because it's fun, because it offers maximum damage consistently)

In your imagination, unconsciously, when you think of a balanced party you think of 2 melee, 1 caster and 1 pranged. And throughout Endwalker was objectively the best thing to have, given the 6-8% difference between melee and the others.
Well a balanced party is 1 melee, 1 caster, 1 pranged and a free spot.

If the RDM did the same damage as the melee, the melee would still have their space, but it would allow the RDM to compete much more easily at the caster spot because it will do considerable damage plus its versatily and could compete for the free spot.
