My 2016 is the first MBP where I've felt that. I have huge dents on it and it's in a Thule laptop bag if it's not on my desk. I'm not exactly gentle on my backpack but I never had to concern myself with my old 2015s (had a couple of these). I rarely use it outside of work, I take it home just for emergencies and it sits on my coat rack in the bag.

And you know what I'd totally pay $3k for a full on desktop replacement that does what I do with it. Fatten it up, give it better thermals, removable batteries, make it MORE durable, etc. I remember using 12lb Dell laptops. We're past the point of diminishing returns on portability now.
