I think all the walktroughs are fun untill you complete nightmare.
When you first enter Hell (mainly with melee champs) the fun goes away and all is left is the bitter feeling of how week you are to do this on P8.
If you ask me,do some limitations with casters (using only rare, magic, or crafted items)- this can result in some nice itemfinds from items which normally are not even picked up.
Dont do any limitations for melee champs bcs you will stop playing them once you enter Hell mode...(talking about P8 of course)
