I just asked several of my friends of the question that what their favorite zones in wow. There are their answers:
My favorite zone has to be Ashenvale. The music choice fits perfectly with the beautiful scenery and it is the first place I visited after reaching level 20 and the cap of my trial, convincing me to buy the full game due to the sheer awesomeness that was promised to follow judging from the epic battles between night elves and orcs. Heading back there now brings back feelings similar to that of arriving back home after a long period away. I make lots of wow gold there,
My favorite zone would be close between the current Stonetalon Mountains and Ulduar. Unfortunately for Stonetalon, Ulduar wins the medal. Ulduar was, in my opinion, the greatest raid Blizzard has made. It was a unique raid that involved coordination and had many unique fights. All of the content in Ulduar was released at once, unlike other large raids such as Icecrown Citadel or the Sunwell. There was no early attunement like there is/was for Molten Core, Blackwing's Lair, Naxxramas (Classic), Tempest Keep, Serpent shrine Cavern, Black Temple, Hyjal, and Karazhan. Blizzard mixed a lot of the fights with fun and coordination, making it overall a very fun raid. I don't think there will be another raid like Ulduar.
My favorite zone without a doubt is the Eastern Plaguelands. It's one of the most interesting questlines ever, few things are more epic than Battle of Darrowshire and feeling al the sadness around little Pamela. Not to forget about the charismatic’s characters we found along the road with Fiona's Caravan, getting you into all the pride and honor of the Argent Dawn along Gidwin and Tarenar. You may just buy wow gold to enhance.
I always loved Nagrand for the art style and scenery. I remember watching my friend play in Nagrand before I was high enough level to get out there and it was a goal of mine to at least level up enough to be able to go there. I still spend time out there to this day. I just finished the rep grind for The Mag'har on my Death Knight. And I finished getting all the Research tokens for the two mounts from Halaa. I might actually be burned out on Nagrand for a while! Cheap wow gold should not be a problem.
My favorite indoor/instanced zone is Karazhan. While it was the base level raid in Burning Crusade and nothing very impressive after T5 and T6 dominated, I still loved it and would prefer to raid there (even if I didn't need any gear).
My favorite zone would have to be the new Redridge Mountains. The Rambo questline is epic as hell and makes the entire zone so much fun compared to the snoozefest going through there was before the Cataclysm. The culmination of the chain where you drive a tank with Corporal Keeshan on the gun just blasting the hell out of everything: orcs, dragons, anything in your way.
I remember almost 5 years ago entering that dungeon with my guild for the first time, and just being amazed at every turn. It felt so much like an interactive Disney ride! Then, at the end, with the climactic battle on top of the giant pirate ship, that was my first "Oh HELLZ yea!" moment in Wow. That’s when I knew I was hooked.
