But how do you proportionally resize the swing? Even if you did, it wouldn’t give you the same type of joy as when you were a kid, because you have grown up and changed. Even if that wasn’t the case for you, you have to consider that the swing has become a place that is sacred for many other adults. When they visit, they aren’t visiting to try out the new adult-swing. They want to try the old swing. The one that brings back the joyful memories of distant past. They know that the experience isn’t the same, but if they close their eyes ... even for a brief moment ... they just might get that nostalgic thrill that brings them back to a time where things seemed so much simpler.
A new quest will pop up once your first pet reaches level 3. It will send you to either Audrey Burnhep in Stormwind or Varzok in Orgrimmar. These trainers will offer a quest chain to battle specific Pet Tamer NPCs on each continent. Defeating each of these NPCs will reward a nice chunk of experience for your pets, as well a Sack of Pet Supplies (which has the chance to drop the Porcupette companion, among the always-useful pet bandages).
One player said in a comment posted in response to the list, “Yeah people don’t realize the sheer enormity of game system evolution WoW has gone through since release. I’m not the biggest fan of BoA by any stretch, but I’ve played since closed beta vanilla, and I doubt I’ll be going back to classic. Leveling was painful. Experiencing these old systems once was enough.”

The vanilla WoW Horde leveling guide you see on this site was originally made back in 2006 by Joana (AKA Mancow, or FuriousPaul).  The guides have been tweaked many times over the years to make things "faster".  The leveling guides were made because of all the messages I got from people asking me how I was able to level up so quickly on new realms.  I was first to level 60 on 7 different realms (3 with Mancow and 4 with Joana), even winning Blizzard's "First to Level 50" contest they held back in 2006.

Well, I think, a “wall of of text” is not defined by the amount of characters. To create a wall of text you need two things: lots of characters, and lots of missing line breaks / paragraphs. I’m completely aware of that, and I’m always trying to section and format my texts in a manner that makes it usable for readers ;) I think the limit of 990 chars is not contributing to avoid walls of text. (It’s easy to build a a wall of text with only 500 chars, but I think you got what I mean…)  

It was the experience of the game that brought pleasure and joy, and that's what a lot of us want again. Not the numbers. When I play Classic I want to go through the deadmines with people I like and overcome a challenge together and see myself become stronger as a result. I don't want to play Classic so I can say "booyah! That number is exactly the same as it was 13 years ago!"
