Lol I used to be seriously addicted to WoW at one point. I played around 2006/2007. I had days when I wouldn't sleep like two or three days in a row just because I was busy with some quest or a group riding. Though I'm one of those people that don't like when something gets TOO much attention, so when everyone in my town started playing, I stopped (which is the same case with Warcraft 3 The Frozen Throne).
To be honest, I'm not sure at which server I played, nor how my hero was called, I just remember it was a 80 level human paladin. I did made a second one, but I only got to level 30ish with that one, it was a night elf (I don't remember what exactly it was, but I -think- it was a hunter).
Anyway, that was my game on the official servers (where you pay to keep your account), before that I was just playing on those silly free servers that go down after some time. Plus they let you earn more experience and you level up way faster. It was fun really, but I stopped playing it. It was taking too much of my time and EVERYONE was playing it so I got kinda bored. Now I don't even know what's happened with the game, are there any major changes? What's that Cataclysm you mentioned? I'm definitely not getting back to playing it, but yeah, I have some cool fun memories from it.
