I think is a really good idea. I have to say the class system is cool... But too simple to perform custom playsatiles. Is only a few playsatyles u can reach whit class system: melee whit mage. And mages whit... Second wind.

This will be good as job and subjobs sytrm in FFXI. Lettg you to decide play as a PLD whit diferent types of weapon, which means duferent strategys and subabilitys.

And i will have no problem uf there will be some tipes of restrictions. Like if you want be PLD only can use weapons of slashing type. Or ranger use ranged weapons. Or monk use only blunt type weapons. Thats my think
