I rolled on a server that isn't hugely overpopulated unlike what a lot of people here seem to have done.
Was one of the first people online and enjoyed watching the starting zone overflow with people within seconds.
Ran from Northshire to Teldrassil, once I got there the servers had stabilized, so I was able to play with no real issues. There was some competition for mobs, but all you have to do is invite people, who are often more than willing to join, and tackle the quest(s) together, who'da thought?
Got to level 9 so far, but was going at a slower pace than most so that I can really enjoy myself, and also so that I can better save for my skills and mount.
All-in-all great experience so far, and I'm absolutely loving it! I had to force myself to log off and go to bed because I had work in the morning lol.
