Guild Wars 2

Since about all I do is wvw, is there anything important that I’m missing? I’m a lvl 80 thief with 3 gold. I’m betting I’m missing something. Any helpful pointers?

If you enjoy WvW, than by all means keep doing it.
For a change of pace you might try some sPvP. Doing tPvP on the weekends has helped me gain much better that I apply when roaming in WvW.
Also, if you ever need to gear an alt, than the Badges of Honor I assume you’ve been accumulating will serve you well, however, you’ll need at least 10g to fully gear a new spec in Exotics. The easiest way to make money is probably running CoF Path 1. You can make about 3 gold an hour there. Do that a couple times every week, and funds shouldn’t be an issue.
Hope that helps!

what’s CoF Path 1? Sorry, I’m new to this game.. barely made my 1st lvl 80 char..

CoF path 1 refers to the dungeon citadel of flame and doing the first path. the way dungeons work in this game is when your group goes in you pick one of 3-4 paths. Path 1 in CoF is very easy once you know how to do it and people run it alot to get money.
