I recently cancelled WoW and went back to DAoC, I'm not playing it much but I just find it more rewarding even starting from level 1 on a US account instead of EU.
There's some things about WoW that I loved, the interface is excellent, it runs smoothly even on low end PCs and on the whole the people were great. However I find that DAoC offers better PvP (by a mile) and more to do at the higher levels, infact it might offer too much to do!
Miss lots of things about WoW but one thing that really annoys me about both games is people using mulitple accounts. There's no way to stop it but I wish everyone was limited to one, I'm playing DAoC on a US classic server now and don't feel I "have" to have more than one account as most people don't but on WoW a lot of people seemed to have 2+ and I didn't really see why!
