The new Jewel Boxes that can be obtained from the Karma merchants. These boxes will give you liquid karma which can return the karma it costed to get the box in the first place. I have noticed a return of anywhere from 50% to 130% back making these items able to be rebought over and over again. Is this something the community should be concerned with as an exploit that anet could possibly perma ban people for?
Stacking those liquids with guild banners, guild buffs, and boosters is what is giving the advantage of extra karma.
Some quick answers from anet would be much appreciated so we dont have issues like the Snowflakes gave us.
