I've been thinking about how each faction can only explore their area and I can't seem to figure out one thing. Each starting area is totally different so won't the quests be as well. Potentially wont there be entirely different 1-50 leveling for each pact? If so you can have a different character in each area and get hundreds upon hundreds of hours playing totally different content, three times the content to be exact. There is just no way each factions 1-50 quests can be the exact same. They'd be like entire different games for each section.
There may be an explanation I don't know. I may be leaving something out. To me it would make more sense to have each faction have their starting area be only their capital city doing 1-10 leveling then everyone could explore everything and do the same quests. I must be leaving something out. Hmmm ......
