GW2Power.com calculates your ‘Effective Power’, which can be directly translated into direct damage (but does not include condition damage). Buffs and vulnerability are all taken into account and can be switched on the fly. It can be used for PvE, PvP and World vs. World, but is focused on the latter.
Unlike many other sites, you do not have to worry about losing data: as long as you do not refresh or close the browser manually, you can go anywhere on the website without a worry.
