During the first week of guild wars 2 a ton of people reached lvl 80 through crafting before it was fixed, since they no longer have a incentive to play far fewer people are playing.
I’d also like to bring up excessive botting going on, I always see groups of 4 toons with similar character names teleporting around, sliding around and attacking at the same time, for instance a group of rangers all looked the same, all had the same pet etc. This is really hitting hard when your trying to do tasks but the bots are using all the resources in the area. Changes need to be implemented to make it harder to bot.
