Guild Wars 2

Hi, I recently purchased guild wars 2 and only know so much about the game. I am curious to how the game runs. Are there a ton of quests? are there skills to level up and will take me a lot of time to finish max? Or is the story mode short and the leveling short and this game is strictly just for PvP purposes as well as PvE dungeons>

I have 250 hours on 1 character and over 350 on all. I have some afk/chat time, but not that much. I am at 79% world map but probably pretty slow doing that. I like to explore every nook and do lots of events.
