I understand why people wouldn't like this current system in the game, though. The major weakness of it is that once a rotation is built there is really not much reason to expand upon it. If anything expanding on a rotation that is established is more likely to break the rotation than anything else, or create problems where the rotation changes across different levels like it was for the BLM. The only option they have to expand on the game is to make new cosmetic options through new jobs, and eventually its just going to be the same job but a different look.

That was the primary advantage older MMOs had that were tactical. If someone needed a new option, they could add one without it breaking anything on the class or job. They also could simply update the cosmetics on certain skills if nothing needed to be added, like making a bigger holy spell animation via a trait.
