For those people who played WoW or Aion or any other MMO... think about how the game used to be at release and then think about the huge amount of content and other stuff that got added later on. I am sure GW2 will be like that as well.
Even with the good state that game is at right now, there is a lot of stuff that could be added in the near future. Different people have different opinions on what to add first and what is needed, however.
The sPvP needs some work and a lot more variety, so does PvE content. Atleast that's my opinion.
I wish you could trait something like "place banner on your back instead of ground". Allowing you to carry it around and use your weapons at the same time. Maybe use it in your offhand only while having a different main hand weapon.
