Has is been said if when you go to another alliance's area for the 50+ and 50++ content, are you then able to play through that alliance's storyline and quests? Or are there new quests tailored for your faction in those areas? Or are there not even quests at all? But you're just going through those areas to find the skyshards and do dungeons and so forth?

You can't enter the other factions' territory. You will need to start a new character of each faction if you want to see it all.

The only area that is common is Cyrodiil, the wpvp zone.

from what i understand 50+ and 50++ have their quest and mobs scaled up to lvl 50, otherwise its the same

Pre 50 level quest are the start of the story line, to finish the story line, one must do 50+ / 50 ++ content. From my understand, to do all the content, one must play all the fractions with a new char and do the 50+ / 50++ content.

We dont have any information about 50++ content beside you will be able to visit other faction territory and it probably be hard as hell

Haven't been staying up to date on the game news eh? They announced months ago once you hit 50 you can go to the other alliance's areas. You can explore the entire world with 1 character.

So apparently after some answers on another forum, Paul Sage said you go through that faction's storyline and quests. I like that, don't have to make an alt to experience all the story

It will be interesting to see how that works out. I like the idea of exploring the other faction areas a great deal but would I for some reason be dropped to level 1 or do you explore as a level 50 and the quests are scaled up?

If you are dropped to beginner status there is no difference to starting a toon native to that faction.

It will be scale up, thus the name of 50+ and 50++
