Current State of End-Game Contents - A Blog Post from A Japanese Player

[Susanoh]

To summarize, I feel this specific writer either can't handle mechanics themselves, or feel they're at the mercy of other players that can't, and want the battle system watered down to where it becomes so simple that people barely have to think or react.

I took from this the complete opposite. The original author advocates dynamic fights, which would require more thought and reaction than what we have now. What he wants is less fights that require memorization to succeed, that are seemingly unforgiving to new players but are trivial and boring to players who already know the fight.
