True. I’ve seen Korraks go as fast as 15 minutes, but I’ve had a guildmate who got stuck in one where both sides turtled and it took a solid 5 hours to complete it.
Talking about Heirloom Gear is all well and good, but while it is account bound (once you buy it, you can load it onto any of your characters, Alliance or Horde), if this is your first character, it’s going to be a bit expensive to get.
As well, when these people are talking about /played remember that 4 days of /played equals 12 days of real time if you’re playing 8 hours a day. If you’re only doing 4 hours a day, that’s 24 real time days. And while you’re gathering /played time no matter what you’re doing, if you’re RPing or just travelling, you’re not gaining experience which will lengthen your time.
One last thing I would recommend, if you can get good bag space early on, is to pick up 2 of the 3 gathering skills Herbalism, Mining and Skinning. Every time you use the skill you’ll gain experience which will speed up your leveling.
But more importantly than SpeedLeveling is to have fun.
