Lately I have been able to verify that some abilities unlocked in the green area of Champion Points have no effect or do not respect the guaranteed percentage.
1) Plentiful Harvest, until some time ago it worked, but not anymore. I keep it slotted and that's at the most so it has to guarantee me 50 percent double harvesting of materials. In fact, I notice that the materials I harvest are about 10 percent double.
2) Cutpurse's Art has never worked well, but now it's really at its lowest. I have done endless tests with and without having slotted this Champion Point. The result is always the same: out of 100 pickpocketed items, 10 are blue, 40 green and 50 white, both with and without Cutpurse's Art.
