I'm kind of on the fence w/ this one. I feel GWEN doesn't live up to the high standard I see in Prophecies, Nightfall, and Factions, so I may just skip on it. Sorry ANet, but you kind of dropped the ball there...
I didn't spend $30 to buy the bonus mission pack. I bought GW:EOTN, and more slots so I could create a character specifically for EOTN. The bonus mission pack was just that...a bonus. In fact I haven't even played any the Bonus Mission stuff yet. I'm still working on the other campaigns. I'm afraid to blow the storyline experience if I jump to the BMP before I finish the campaigns.
