Well, I have to admit that I am stuck at the MSQ duel with a certain entity of light. Just a friendly duel...ya right.
I don't whine about it, I just do other stuff. It is what it is. I don't need everything if the game demands I do things I don't enjoy.
I spoke with some "veterans" of the game and even they said it was a brutal encounter that tested their abilities to the limit. As I am a casual player it is highly unlikely I will reach that level of skill. My game now consists of hanging out with friends in town and making music. I don't feel a compulsion to finish anything if it stops being fun.
The best way of handling it is to do what you enjoy. If it's too difficult, forget it. Do something else. Try to have fun instead.
