I actually don't have as much trouble fighting OK now as I did before. I fought him extensively on Quick Battle to learn how to time his moves and can safely do that most of the times.
The only one I still have mayor trouble with is Cloud of Darkness, it's almost impossible to figure out a pattern for her ._. especially if it is a Maximum one. She always seems like she's going to attack with her sphere tentacle BRV attack and then out of nowhere, bam, 0-Type Beam, or a Fusillade spam....oh god how I hate Fusillade...
