At each of the karma vendors you’ll notice signature stats for use. The build I’m working on requires Toughness + Vitality + Power as a signature combination. Here’s the catch. There is no pair of legs in game with this option for light armor. There’s this option for every piece of equipment EXCEPT the legs. So, my suggestion is as follows: Give us a karma vendor that sells this option set for legs. Change the stats on one of the legs to match this combination and all is well.
If you think I’m wrong, check out each of the karma vendors.. or check out this link: http://dulfy.net/2012/09/08/gw2-templegod-karma-armor-sets/
That’s all I have to suggest, otherwise I love the game to its fullest extent!
