Guilds wars 2 needs a lot more than what you mentioned.
1. PvE: receives a lot of updates, but always with the casual player in mind, more competitive players do not have Raids or new Instances, at most one Strike Mission CM per Expansion;
2. PvP: PvP is great content, but it is outdated, they need to adjust the Match Maker system to avoid bots and match manipulation, impose punishments for troll players...
3. WvW: this is my favorite content, and I agree that they need to pay attention to this too. But I think there is no point in any content updates for WvW if the main problem has never been and will not be resolved anytime soon (SKILL LAG). They recently announced some improvements that will come to WvW, but for me there is no point if it doesn't solve the problem with LAG on the server during fights with many players.

ANet likes to release good content, the combat system is perfect! But there is a root sin that they always commit, which is thinking that the content is perfect and does not need changes or improvements...
Sorry for my English, if it wasn't clear.
