I agree with GoktimusPrime on this one, Beast Wars actually had beasts/animals/insects etc transforming into robots, whereas ROTF Ravage transforms into some weird thing that just looks like his legs are covering his head

so they're completely different in terms of engineering, whereas BW toys have to hide robot-only bits and pieces... Ravage doesn't really have to hide as much stuff

anyway if you have too much articulation, you'll have more joints, and with time, the joints become loose, so even if the beast modes could stand back when they were brand new, they'll start to sag and eventually your toy won't be able to support it's own weight
