Example scenario:
You have both Verstone AND Verfire procs ready with 10 and 25 seconds remaining respectively. You cast Verstone and use up the proc, putting your mana at 51w/53b. You're about to have a lot of movement forced upon you by the fight mechanics, so you're intending to follow up your imminent Dualcast GCD with an Enchanted combo to keep uptime.
If you spend Dualcast on Verthunder in this situation, despite being Verfire Ready, you are guaranteed to exit your Enchanted combo with both Verstone and Verfire procs, since your mana will be 51w/58b upon execution of Verholy (giving you a guaranteed proc). Whereas if you cast Veraero you'd enter the combo with 54w/53b, and by the time your combo ends your pre-existing Verstone proc (if you had used Verfire instead) would have fallen off. Sure, Verstone has a 75% chance to proc between both the Veraero (50%) and Verholy (50%) casts, but it could have been 100%, and if it doesn't proc then you've just lost a free Verstone (assuming the rest of your proc RNG is the same).
While that may seem inconsequential, it is nonetheless a form of skill expression because casting Verthunder guarantees more damage. You're free to cast either Veraero or Verthunder in that situation and the only difference is a 25% chance to lose 20 potency. But a high-skill player would recognize that difference nonetheless and act accordingly.
Additionally, if the Veraero->Verstone and Verthunder->Verfire substitution is optional, but the devs add 2 new skills that are just as important to the rotation and compete with Verstone/Verfire for prime button real estate, the players who want avenues for optimization are now bloated with 2 more buttons while everyone else has the same amount of buttons as before. In other words, from this angle, one group is worse off, yet nobody is better off.
Now, Black Mage's Fire IV and Blizzard IV on the other hand... Please combine those. They can only be used while in their respective, mutually exclusive stances. Please.
