Let's assume that allll of the classes form the PHBs are all in their...exactly the way you want them.

There is space left for onnnnnne/1/uno/un/eins/ONE more class.

Do you use the space for:
A) A Psychic/Psionic/guy with mental powers class


B) A spellsword/swordmage/"gish"/guy with a sword who casts spells class?
