When World of Warcraft launched in 2004, all the lore, history, and Wow gold classic locations that was laid out from the earlier Warcraft games were attracted to life within Blizzard's vast MMO.
If you've just got a couple of hours a week to dedicate to an MMO, Classic may not be the match for you personally and you might be better off considering modern Warcraft to fill that Azeroth-shaped hole. Having said that, if you're not particularly concerned with endgame content such as raiding or max-level dungeons and only wish to explore Azeroth because it was in 2006 then by all means, carry on. But if you want to enjoy everything that Classic has to offer, then you need to be prepared to spend a lot of time not just levelling your personality but completing different Attunement quests and grinding standing to get a few of those late-game cases.
World of Warcraft Classic doesn't have those quality-of-life improvements that you may be used to in contemporary Warcraft - or really many other current MMOs. For starters, the climbing of cheap wow gold enemies is a whole lot less forgiving and you could find yourself getting quickly overwhelmed it you simply take on more than two enemies simultaneously without preparation. Travelling from one spot to another in Classic Azeroth is also much more time intensive - flight points aren't as plentiful as they are nowadays and using in-game gold less easily come by, you can find yourself unable to save up to even buy your initial Riding Skill and mount.
