Oh, I definitely agree, even though I'm biased, since I can use and have used Ngold (even if it wasn't on FKG, at least not yet). However, some would still raise a sh!tstorm, because what's meant as a little bonus to some, would be perceived as a handicap to others who aren't entitled to it. So, even if the effect is there, I think it's relatively small, and hard to notice for those who aren't paranoid or analytical.
But, what I perceived, that if I ever do plan to use some nGold, I'd use it right before using some 50 flowergems I had laying around anyway, instead of using nGold to try for what I failed with the regular flower gems.
