I would like to add my own thoughts to this matter.

Instead of Red Mage coming from the fusion of Conjurer and Thaumaturge, why not have it instead be a branch class of Gladiator? The requirements would be Gladiator 30/Arcanist 15.

My reasoning behind this is thus: Arcanists have spells that take from both sides of the magic spectrum (attack spells like THM and healing like CNJ) whilst still retaining their own unique mechanic (summons via Carby/Egis/Fairies). So therefore, in exchange for a Gladiator forfeiting their shield, they can now use a limited amount of magic.

I mean, if you think about it, the ORIGINAL Red Mage was designed to be a hybrid of both magic users, whilst surpassing neither in terms of actual magical prowess. So Red Mage becomes a DoW hybrid, rather than the DoM hybrid that Arcanist is capable of being. Not to mention, Yoshi-P needn't make any new types of weaponry to accomodate this, as all he would need to do is create a couple new AF/Relic armors & weapons, and keep shields exclusive to Paladins and non-Red Mage'd Gladiators.
