It's not about difficulty, it's about having the best of both worlds between RP and gameplay mechanics. If you want the most story and quests and cool dialogue options, the pre-generated characters are the way to go. Sebille has the rogue and scholar tags, let's say that gives you finesse and memory, the player is once again nudged towards the scoundrel or huntsman route. It's better than the current system but nothing fundamental has changed.
