Just because you personally do not experience a thing...
...does not mean that the thing is a myth.
I've never had caster dominance, never had people refusing to play "homebody halflings," never saw a well-implemented skill challenge, have never personally measured climate change, have never seen the constellation of the Southern Cross, and have never been to New Zealand.
Pretty sure all those things are still out there.
Well, maybe not New Zealand. I mean, come on, kiwis are waaaaaay too ridiculous to be real, guys. But the rest of 'em, yeah. Pretty sure.
