You could also start tying a lot more systems to be affected by "speed" — such as autoattack-based procs, dot-tick-rate based procs (and allowing Haste to accelerate dot tick rates), etc.
...That said, trying to implement this in XIV is more-or-less a lost cause, especially without dismantling the extreme gains from piling everything into coordinated buff windows (which has, for example, helped to push SpS Summoner further and further into the margins each new gearing tier), and the game's opposite-direction design moves (with, eg, dots being wiped-out), and the game's priding itself on precise and exact encounter timelines, and... etc.
So, I guess the fundamental problem is really that "going faster" as a reward tends to fight XIV's entire design and structure, and become more of a wet-squib or even a punishment.
At this point, can that even be "fixed" ?
