There's only about a week left of Ask a Beta Tester, so get your questions in while you still can! You can be special like Radiophonic and get your name all bold-like up here! I guess we could actually answer the questions, too...
So I'm hearing that there are tons of quests in all areas, has the allowable number of quests in your quest log expanded or should we all start getting those last 10 or so completed?
The number of quests you can have in your log is still limited to 25. If you stick to one zone at a time, it's very highly unlikely you'll ever have more than 15-20 quests in your log at once. If you're anything like I am though, curiosity will probably get the best of you and you'll end up questing in 2-3 different places at once and you'll need that space in your quest log.
You might want to finish up the quests you have now, or when Wrath comes around you can scribble down where you got them, abandon them and go back later.
