Red Mage "better"??

Ultimately it doesn't matter, line up with CaC doesn't matter, you have plenty of time to run in range when you see you're approaching the mana level of melee combo, it doesn't ruin anything, you don't have to spam reprise, you don't have to lower your mana, just literally walk to the boss during a dualcast window and you can melee, because being able to reposition in dualcast also happens to be a flavor of RDM.

I don't know if you and the other guy are expecting the devs to hold the "dash in - melee - dash out" as if it was some immutable canon.

Also if the dev intent was just the visual aesthetic they would have removed any potency from both movement skills, as long as RDM has RNG procs and those skills have potency they won't always line up. The fact that they keep the potency post 5.0 changes means they are okay with the way people are using them as ogcds, and they even added a high payout / low payout version of the disengage skill.
