IMHO its really a way by the top bureaucrats at the IFBB & Co. to snuff out women's bodybuilding! There's just too many categories now - a sort of "never mind the quality, feel the width" scenario - the crop of athletes are spread too thinly, and that the new "Physique" category is just for female bodybuilders who wan to be one weight category down/less ripped, but without being penalised. Its a bit like saying there should be another 100m athletic race at the Olympics for athletes who aren't quite as quick as the top ones (figure vs FBB is different - the "look" is quite defined, whereas the new "Physique" category doesn't appear to be).
Don't get me wrong - many of them look really attractive, and it may suit some women (Katka Kyptova being the best example - she was never really big enough to win a pro FBB show, and probably pushed her body too far [detrimental effects started to show] - much better now), but the IFBB et al should've changed the existing weight categories and judging criteria in FBB to suit. Maybe having decent awards for "Most Muscular", "Best poser" and "Most feminine" perhaps?
