If you drive for any amount of time on the highway the inside edge of the tire will be so hot that it will almost burn you, while the outside edge will be just warm. Toyo's camber recommendations are for competition use.

Also, my experience switching from Advans to RA1s was that grip was much better with the RA1s, but turn in response was much worse. When I saw that I was burning out my RA1s on the street, I dialed back the alignment and got PS2s for the street. They feel similar to the RA1s but with less ultimate grip (much better ride than the Advans though).

how did rear tires look? You never rotated them?

Turn in is tunable and not necessarily a fault of the tires. Just altering air pressure can drastically affect how the tire reacts when loaded.

Yes, I rotated them, though by the time I first looked at them the damage had already largely been done.

Dependant on use, but also remember that the Proxes RA-1 is a 100 UTQG, DOT-R compound tire. The RT-615 is not, rather it's more of a street / autocross tire with a 200 UTQG rating.
