I have made horrible choises and i really badly want to redo the perks without restarting my character i've played for oh' so long. I know PC gamers can do it.

So....?

Well, you could just reload to a point before you picked your last perk. And really, RPG's mean sticking to your choices.

I've made some bad choices, but I've just decided to turn them into good choices... on my main character, I have no real purpose for using destruction magic; my character is melee and bow orientated. But I chose some of the destruction perks early on, so now, I try to use destruction magic a bit, just so those perks don't seem quite so wasted.
