Nope i totally agree. I have to crowd the boys cage a little more as we have the brain damaged boy - but the girls need lots of room to ping and play - i like to give them a bit of floor space for wrestling and keep the comfy sleeping areas to the top of the cage. Foods either floor level or v ery low down.
I've seen soem cages on FR that you couldn't swing a rat in because there's so much stuff. It's got all the bases covered, climbing, snoozing and playing. S'all good!
