We talked about them and I did research and set up the differences (in look and stats), and even recruited another artist whose first test was to make them, but he never followed through (it was his second time as a trial member, oh well) and no one on the team ever made the model changes or textures and eventually another unit took their slot. They were finally pushed aside when arguments were made that the difference in regular and heavy slingers (the heavy ones were mainly going to be an eastern version) was not going to be big enough - I just didn't put up much of a fight because I was tired of trying to get it made.
