I don't think SE consider D4 RDM in the mechanics in this patch

I don't see a solution proposal, I see someone wanting to add complexity to try solve a problem with fight complexity by shifting it into the job they're playing. If your goal were to actually reduce complexity or keep it equal while improving red mage potential, you'd simply shift damage from the combo into the filler, including overhead for the burst potential reduced. Tuhdaaah, same damage in uptime fights, improved damage in disengagement fights. Increased damage in fights with breaks like Ultimates, too!

It's the exact opposite though, this doesn't add complexity. You're turning a currently tricky problem "Trying to execute your melee combo with no safe spot near the boss" into "Lol just ranged combo".
But yes, at that point just remove the actual melee combo from rdm because if potency on both is equal then "Lol just ranged combo" becomes the default anyway.

That was my point, exactly. If it's just about "Oh I cannot melee at the right times and clearly this is unfair and not okay" then the correct solution is to eliminate or factually-eliminate the melee combo (an opinion I do not share, if that wasn't obvious enough). Adding an extra ranged combo is absolutely pointless, because either way you're just standing at range, might as well just remove the melee combo entirely then?
