Frames have IMO actually gotten better. the KOP frame has a lot better durability to it than the KOP frames from 2004 onward. In fact, I would say it is nearly equivalent to some of the best from the 2007/2008 timeframe.
Deformation comes from energy. and Kinetic energy is KE=1/2*m*V^2. In 2007, most defenders only traveled at about 7 FPS or less. Now, may are hitting 10 FPS with some teams exceeding 12 or 14 fps even. When comparing the two, a 7 FPS robot has 1/2 the kinetic energy of a 10 FPS robot. 12 FPS robot is at 3X a 7 FPS robot. 14 FPS is at 4X the Kinetic energy.
I help kep a lot of teams running during the weekends, and this year, I am seeing a lot of fallout due to wires getting pulled out during high speed impacts. Its a rough game.

I was actually not speaking of the KOP frame, and you're right that it's considerably better than previous years (though I still thought the older ones were fairly durable if assembled right). I just remember when we used to build our robot frames out of ~0.25" aluminum plates because there were no bumpers (granted, this could have just been our team, but we never had a bent frame).
I will admit my experience is limited to 2005 and later, but still, I don't remember seeing nearly as many of
THESE problems back in 2006 and 2007, and as I recall there were some pretty speedy robots in those games, maybe they didn't all have 6 motor drives (though ours did in 2006), but there were definitely robots that could get across the field very quickly.
