Quote from this weeks design notes about new class:
"You will need to turn in the quests and re-accept them every time. We've been forced to take this measure to help combat botters so you can thank those people if you find that a little annoying.
So they haven't found a way to stop botters have they. Getting a little feisty there don't you think AE? Maybe they don't realize, but bots can auto turn in and auto accept. Some people must've not done their reading on bots.
