I believe the rate drops again after 70/71.

After set 51, stop exploring chapter 1/2 and try exploring around chapter five. The gem drop rates seem to be higher.

After set 71, try around chapter seven or higher.

pvp is somewhat working - it' weird but I have found about ten people to battle so far, mostly higher levels people who haven't completed sets yet, probably.
