Can future relic weapons have special abilities?

[Zojha]

FFXIV's biggest weakness is boring stats on gear and inability to customize our combat at all[...]

Which I do not find much of a weakness at all to be honest, largely because I never found stats particularly exciting. I can agree on combat customization to a degree, and that degree is the limitation to gameplay changing effects.

Simply put, if the customization doesn't change the way I play, I'd rather not have it at all. I don't need customization when I still do the exact same rotation with the exact same abilities with the exact same positionals while hammering the exact same oGCDs. New skills with new purposes, that is interesting. New/different effects and uses for existing abilities, that is interesting. A passive procc that randomly grants extra DPS is not.
