Well obviously it's not a constantly recurring issue to accidentally cancel your spell, it's not like it was my main point anyways, lol.

FFXIV combat is only unique in the sense that there's animation lock, really. And also it's not at all demanding so you can have a whole conversation on the meaning of life in your linkshell while you wait around in between cooldowns, etc.

In instances, there's usually enough happening that it never seems boring, but when youre soloing, that's when it becomes especially obvious. I pity new players who will have 1 ability to use over and over.
