ok i ll explain better. My idea is that in every chapter just after the player beats the last boss and he is famous now, two ''sects'' come to speak tou him. one sect is the good side, the ppl who want to use the new hero as an example of greatness and as a weapon in their on going fight against the second sect the evil side. now on their behalf they approach the hero and try to lure him with promises of wealth and power if he helps them with their cause. Then you have to change which side, eachside gives you more missions to do in order to gain new titles that have to do with the side you pick. Moreover new areas should be added in every chapter instead of creating a new continent, Large areas and different than those we havealready explored like posh areas of kaineng or tropicalislands in Proph and icymountains in NF where the new missions will take place.
OK more details about eachside.
First of all each side will have its ownset of titles like i said and as you progress in rank new PvE skills will be available, the lightbringer idea was good but now well made i think.
In addition to this, more armors will be available and weapons that only drop in good or evil areas, armors thatr limited to each side and they reflect the good ot the bad of their choise. Please no more armor that looks the same as in all chapters the difference between them is minimal when it comes to elite ones, only difference is the number of horns and spikes on them.
Moreover, i think the appearance of the character it self should change ( this is an idea from fable i guess but GW isnt supposed to be a innovative game afterall) like paragons should have black wings and good paragons milk white ones

Now to give solutions on some of the problems that might arise.
-lets say you start your good bad campaign in NF and you finish all the quests you have there if you go to cantha will you have tostart from the beggining???
-No, the whole good/evil campaign will have a fixed numer of missions no matter where you start. if you finish the quests in one campaign then by going to the others you will have to do different quests than the others that started there would or to make it more simple you would do the same quests but you would view different cinematics and have different rewards than those that started there. just like with on going campaigns. Maybe here a safe precaution should be added like a character could start the good/evil campaign onloy in the continent he was created and when trying to do others in other campaigns there should be a foreign or local district like ina couple of missions in Factions.
Finally in order to live up some of these missions anet could make them PvP like a couple in factions too, Imagine good vs evil

Now any questions or doubts you might have shoot away
