I like the karma. It goes great with the post count, because some people just spam posts, so you cant tell if they are helpful based on their posts. Then you can look at the Karma, and know if other people thought they were helpful. I dont look at Karma and say that if a person doesnt have a lot of Karma, then they arent helpful, because some peoples posts just arent viewed by people that give karma. However, if I see a person with NEGATIVE karma, then I usually dont look too carefuly at what they said, especially if it is critical of whatever I said.
Now on the other hand, I dont think Karma should be allowed to be given out for things that are not elements related. Yes, I think the person made an awesome forum game, or THey have really awesome perspective on religion, however, I dont think they should get Karma for it, because someone could have a lot of karma for forum games, however, they really know nothing about deckbuilding or actual elements related stuff.
Card art, relates to elements, so it should count, forum suggestions, I really dont feel should count, because that relates the forums alone, and not the game. I think that Karma should be for the Game related Elements activity only.
