Why did you buy the game? For the lore before GW2 comes out? The HOM rewards? Or to have fun in whatever way you like to? And which campaign did you start?
Like MayISing I bought the game 4 years ago got bored and quit and didn't come back until about a year and a half ago. I bought the game for the MMO experience but didn't want to pay a subscription fee or have to pay for hidden charges (if I ended up liking the game). That's how I came across GuildWars. The RPG/fantasy aspect also apealed to me. But I couldn't get into the story line (prophecies still bores me).
Until someone showed me how to properly make a build and distribute the attribute points, I was just runing around hitting things. But once I understood how to combine skils into a build set and the strategy involved I began having a blast. I also joined a guild that's big on builds, strategy, PvP, and playing PvE with out grinding and farming.
