Why do we need a disciple of war/magic to unlock leves...

Fighting class is also optional and not mandatory in the sense of you do not have to do fates, do dungeons, complete main storyline or bother with leves to level up your trade or field class. As such they all become optional activities by proxy DoW/DoM also become optional because of this. You can level crafting and gathering to max level without doing those things including not having to do leves. As long as there is choice to do something or not even how you do something then it remains an optional aspect of the game. As far as I am concerned leves should not even need to be unlocked ideally and especially not with a class different to the type of leves you want to do. Perhaps they should only use DoW/DoM to unlock battle leves while leaving DoH/DoL to unlock field and trade leves if didn't mind meeting me half way on such an idea.

The game design explicitly shows that a fighting class is mandatory,
as you need to select a fighting class upon character creation. ^^;
