This stems from the current thread started by someone who is upset that people prefer to look good over having awesome stats.
I have a proposal that I believe the Materia system can implement into the game.
Currently stats do not matter, but in the future they should after all the rebalanced and combat changes go into effect. When that happens obviously people will start taking a greater look at the stats of gear over the looks of gear. This will upset certain players. Especially people like me who prefer looks over stats. We don't intentionally gimp ourself into unplayable gear sets but we tend to mix and match gears that look good while giving us at least some beneficial stats, bu these stats may not be on par with the hardcore min-maxers.
The simple Idea is to allow us to chose fashion and stats together. The Materia system could easily allow this.
A User prefers the appearance of a certain item. Fashionable Coatee. But the stats given with this item do not reflect well with this players Class of Gladiator.
On the other hand the Defenders Haubergeon has the stats and appearance most people prefer for Gladiators, but this player is irked by and uncomfortable with its appearance for their own reasons. These reasons are theirs and we are not here to debate them.
To counter this the Materia system enables a player to take the stats from one armor The Haubergeon, and force them onto the other armor the Coatee.
The Player thus either fights through raising the AP on the Haubergeon and converting it themselves or finding someone who likes the Haub and continuously converts them over for profit to acquire the Materia for the Defenders Haubergeon.
Once they have the Materia they can use a specific catalyst to pound it into their Coatee or find a crafter to do it for them. Using special catalysts as a way to differenciate "Replacing" the stats on the gear or just "Boosting" the stats on the gear.
The Coatee can now reflects the same stats that the Haubergeon had, the old stats being over-written by the Materia being grafted on with its special stat converting catalyst.
The Secondary Slot Materia then gives only the option of boosting only some stats or skills instead of converting the original stats of the gear.
Would this satisfy most players? I do believe it would.
