I looked over the list of spells available to players and, unless I missed something, the only spells I found in the BRD's arsenal were their song cooldowns. Again, feel free to correct me if I'm wrong, still learning.
I concur that it would have made zero sense to have skill and spell speed be the same but different... when they were implemented. I can understand perhaps if the two were intended to be programmed to have different weights (ie 100 Skill Speed being 10% attack speed affecting auto-attacks, versus 99 Spell Speed being 11% cast speed, as example numbers), to which I'm sure the counterargument is simply that the combined stat could be programmed with different weights on each side anyway.The cross over isn't extensive, but it makes zero sense to have skill speed and spellspeed be functionally the same but two different stats.
Regardless, they permeate the game in their current state, which means that in order to combine the two now, the devs would have to take the time and resources to address every piece of gear that provides either one, materia, consumables, etc, as well as rebalance classes that would be directly affected. That's not even including rare cases of items that, for whatever godsforsaken reason, already provide both.
I highly doubt it's as simple as CTRL+F "speed" and copy-pasting down a text document.
Let's assume for the sake of argument that RDM, DRK and PLD have cross-type skills specifically meant to act as fixed GCDs. If the two stats were merged, the devs would most likely need to re-evaluate specifically those skills, and determine if they remain fixed GCDs or become affected by Speed. Regardless of their decisions on a case by case basis, the point is that they are being evaluated individually.
Versus, the devs skipping ahead and simply addressing those individual skills now, and leaving the separate tuning knobs in place. No taking the time to redo what I can only assume to be literal thousands of items.
Which do you think they would prefer?
Most likely because nobody in this thread is actually working on the design of FFXIV, meaning that suggestions do not need to meet the scrutiny of other players, but of the dev team who ultimately decide what and how to balance and program skills. To get into specifics would only serve to invite pedantic in-fighting, on top of creating attachment and hype for ideas that we ultimately have no control over actually getting into the game.
For this reason, it's more productive to argue the broad merits of suggestions, not the specifics.
