hey guys need some help! need some feedback on a few questions hehehe

im a huge wow fan but i left the game during MOP. been hoping around a lot of mmorpg games and i still find wow is the most engaging. im not a huge pvp fan. So im wondering if wildstars pve is good? do they have battleground maps like alterac valley? i saw some videos on youtube the graphics are cartooney, so are the quest stories lean towards comedic side? finally which server are you guys playing on?
