Will you take the time to read the Quest Logs? Or do you just click and accept?
When I first played Guild Wars (my very first CORPG) and well, this type of game was so new to me that I didn't knew anything about it. Everything went really slow. But now, after almost 1000 hours of Guild Wars, I think it will go a lot faster in Factions. I also have read 70% of all the Quest Logs but does it really matter anyway, if you read them or not? They have like nothing to do with "the storyline"....
So: I will not be rushing the game. I really enjoyed playing the FPE last week and only explored a little bit of it. I saw pictures of the fully explored areas and I was like wow, did I missed that much? But actually I'm happy that I didn't explored those areas. Because if I had explored them in the FPE, the "excitement part" would have been gone when Factions is released.

I'm building only 1 pve character to play with until factions is released. So, when factions starts and I merge accounts, I'll have 1 lvl20 character that I enjoy from chapter1 and 5 extra slots to do what ever I like in factions. I don't really enjoy chapter1 anymore since I've done everything, I even shelved the game for 2 months and came back a month ago just to start getting bored again.
