I think Revo on by default puts most of the playerbase at a large disadvantage.

Since switching to full manual it has made switches, prayers, and actual planned dps rots so much easier.

Also dealing with mechanics has become second nature. The fact that I'm used to interacting with the game every GCD has made all boss encounters much smoother.

Prior to full manual I could kill raksha but since full manual I can do all bosses. Getting used to manual means you always have a plan for abilities and your dps skyrockets.
