Why not just respec? do you really want to spend another 40-50 hours to get where you are when you can just respec for a few grand? you get all your ability and skill points back (and the ones you got from trainers are still there too) and if you don't like it just respec again and try other builds. The price is very cheap since you become filthy rich in the game
Well in most rpgs I tend to like living with the choices I've made, the respecc option aswell as fast traveling don't really exsist to me. I understand why they are there but they are features that I pretty much always ignore. I,ve decided to stick with my character for now, might max out longswords to get alittle extra variety in combat. Then once I've completed the majority of the game with my main ill jump in again at some point to try some different build options.
