Yet another Red Mage post, but hear me out, please.

The elemental properties CAN work though and adding debuffs to the weapons is a good idea. Fire can be a DoT for example, lightning could do a chain lightning effect for aoe, ice could slow for pvp, etc.

But then the "fire sword" wouldn't be very different than goring blade, chaos thrust or shadow fang, Ice sword would be another Feint...

Anything below that reduces the job to token status, when the goal is to make jobs interchangeable to a degree without outright forcing people to bring a specific job.

All you need to do is to properly balance its raid utility. A spell like Temper could be very powerful, considering the first version doubled your attack power. RDM could also be the right moment to give us a real Haste spell, since its personal damage output would be lower than every other DPS.
