In your case, I think you handled it as well as possible. At least your fellow group members were willing to try and be involved, even if they weren't technically proficient enough to complete the required work. The whole firing group members, IIRC, was meant to handle people who weren't contributing and weren't even trying to contribute. Basically, those hoping to ride the coattails without expending any effort. It's an iterative improvement over the standard group model, but by no means was it perfect. Honestly, I don't think it's possible to design a perfect group work system. There will always be human edge cases.
