me personally, i enjoy what ive played of WoW more than GW... the part that turned me off was the whole monthly fee. the part that turned me on, was that many of my cousins... about 10 of the some 60 play WoW... so it would keep me interacting with them. As it stands now, I just made new friends...
For me, i would rather see GW2 be along the line of no "cemented" story line. So you can change where the story takes you, and go with the flow... the only problem with that would be the whole.. i have this quest... and oh "you cant help me here because your good and i'm evil" either way, I also agree with someone i saw on the link previously at guildguru... much higher levels ftl... i mean, a level 30.... maybe. 40... egghhhh .... 50... um i dont have time to level all my characters to level 50... so i would say a level 30 character, would be sweet, IF, you could raise the ammount of skill level to 15 or 20 without runes that kill your health
