Karma changes were not done because we wanted to be like Facebook, there were done to make the Karma system simpler. However, I just described the changes comparing them Facebook just to make it easier to understand.
I too appreciate your efforts, but I fail to understand how limiting us to giving out 1 KP at a time makes things simpler. It makes me have to go back 4 more times to give what I used to be able to give. To me, that isn't simpler. Karma is a reward, in my opinion. Some people deserve a better reward than others, depending on the act that brought about the urge to give K in the first place.
Limiting us to 1 is a step backward, and is unfair, really.
Just one more rank perk taken away. Bummer.
