I guess Ezra is the first to unlock it.
It seems more likely that everyone else has been using it all the time, for instance, Natsu was able to use Fire-Lightning mode against Sabertooth when he attacked their guild, without collapsing, and Natsu, Grey, Wendy and co are all showing significant improvement over the previous arc, whereas erza was just being erza.
