Some of you might have noticed in the newest live letter that Despair was cast instantly without Swiftcast or Triplecast.
As a Black Mage, the fun of this class comes entirely from the uphill struggle to maintain GCD uptime, and perform the rotation without dropping enochian.
Paradox being made instant in 7.0 was a change I've been very critical of in the past. It made the rotation at base spell speed far more rigid than it ever was while only granting minimal movement freedom. Adding a third Polyglot stack did enough to enhance our movement capabilities, and I don't see any need to add instants in the main rotation.
On the surface, it would look like Despair being made instant would fix the rigidity issues. You should now be able to get four FireIVs after Paradox again, But I still feel like this goes against the entire class fantasy of Black Mage in the first place.
This class is all about doing big hits with long cast times that you can't move during. Now two of our biggest hits are usable instantly. This is without mentioning that they're the most important ones to time correctly, seeing as they refresh the enochian timer.
A couple other issues I can think of is that with Despair being instant, it might be very easy to accidentally hit it when you don't mean to, and instantly drain your whole MP bar without being able to cancel the cast like you can now. Despair being instant now makes low levels even more worse than they already were. Before level 72, players will have to consider the time taken to cast Flare when it doesn't exist for Despair. This is also something I'd consider with instant Paradox. Players are already used to using a cast time to refresh enochian below level 90. There's no need to make it instant above 90. It just serves to throw off muscle memory and cause issues when level syncing.
There are also good changes in Dawntrail that I won't ignore. The triple Polyglot stack makes movement much more flexible, and though I still do use them to not overcap, I find myself doing that far less. Retrace is a very useful skill, especially for mechanics where your next position is uncertain. The changes to Manafont are a lot of fun, and I especially like that it activates faster, so now we can late weave it.
The double leylines stacks is something I don't really have any feelings about. I was never really too bothered about not lining up burst windows perfectly, but I know that other people are. So if they like it, then it's a net positive, I suppose.
The Dawntrail Black Mage changes have been widely contentious, but I still hope that it gets fixed sooner or later. I don't want a total reversion to Endwalker Black Mage. I just want the class to still feel like Black Mage.
If you ask me, the two things that would fix the class the most are the return of old Thundercloud, sharpcast and the non-guaranteed firestarter procs (I mention these as one "thing" because they can't exist in isolation. they interact too heavily to create the DOT system) and the cast time on Paradox/Despair.
