I'd like to add that I think an VII system would make goals and character progression, etc, more focused. `I'm a Dark Knight. I want my linkshell to get me that triple attack materia, that haste materia, that whatever materia, and i'll be a monster because of it when my awesome scythe has all X amount of slots filled with X (specialized) materia.` Instead it's `I have triple meld strength gloves with 42 STR on them. Maybe i'll try and get more...`
The system as it exists now is sort of a snooze fest, IMO, that just congests the wards and server with so much variety of the same uninspiring materia.

Simplify, specialize, make less of, add materia slots, let us customize. Eliminate materia as a crafters gamble and make it focused, goal driven, progressive and... cool.
