I know it isn't likely, but I hope it is possible we might see an abbreviated version of possible styles, that you could take as an extra starting talent. They would change up your gameplay style/flavor, but come with steep changes. As example:
Barbarian: Jewelry gains a massive percentage of increased physical/magical defense, and the player gains increased movement rate, and massive melee attack damage, but can no longer wear armor, use scrolls, ranged weapons, or magic.
Duelist: Can only equip a single one handed non-blunt weapon and no shield, but gain increased damage/crit, reduced ap cost for attack, and increased dodge/parry
Barefisted: Can no longer use any weapons or heavy armor, gain massive bonus to dodge/fist damage/crit that scales with level, warfare and dagger skills are modified somehow to be usable with fists
Spell focus: Magic damage is increased, costs less the ap to use, and cooldown is twice as quick, but you cannot gain any physical/magical defenses outside temporary sources, like from fortify, and have a penalty to con and movement ap.
Healer: All hostile/damaging spells refresh slower and cost more ap, but all beneficial or neutral spells refresh faster.
