Whether it's talking about rotations, Materia builds, or class synergy, a category to discuss the combat system would be EXTREMELY valuable.

Justification

It would source of information from experienced players to new players. Also it would help developers to understand how a class its abilities are understood and used by players.

This would also be a valuable source of feedback. It would highlight aspects of a class that give players satisfaction, as well as advertise those aspects to prospective players. I think opening discussion could illuminate needs for balance and greatly reduce the amount of times a class (ASTROLOGIAN) needs to be reworked.

Additionally, the occasional poll would gather consensus and employ the FREE energy of dedicated players who want to see this game grow and thrive.
